Judas Iscariot: How Could a Disciple Betray Jesus?

by Joshua Andreasen | Founder of Unforsaken

Judas lived close to Jesus, heard His teaching, and shared in the work of the Twelve, yet he became the man who betrayed Him. His appointment was real, and so was the unbelief Jesus exposed. His later remorse also requires more than a quick judgment about how sorry he felt; we need to consider where he turned when he recognized his guilt.

Judas Stood Among the Twelve Without Saving Faith

Judas is the Greek form of Judah, a Jewish name associated with praise. The Gospels distinguish him as Judas Iscariot but do not explain that surname. A long-standing explanation connects it with Kerioth, a Judean town named in Joshua 15:25, giving the sense of a man from Kerioth. That derivation appears in Thayer’s lexical entry for Iscariot. If correct, it could make Judas the only Judean among apostles generally associated with Galilee. Other explanations have been proposed, and Scripture does not settle his place of origin.

We know nothing definite about his childhood or previous occupation. Nor does Scripture identify him with a political party or tell us every motive behind the betrayal. It does tell us that he received an extraordinary appointment from Jesus Himself (Luke 6:12-16).

Now it came to pass in those days that He went out to the mountain to pray, and continued all night in prayer to God. And when it was day, He called His disciples to Himself; and from them He chose twelve whom He also named apostles:

Luke 6:12-13

Jesus prayed through the night before choosing twelve from among His disciples and naming them apostles. An apostle is a representative sent with authority from the one who sends him. Judas genuinely held the office Jesus gave him, even though Luke also identifies him as the man who became a traitor.

I need to distinguish an appointment to ministry from regeneration, which means being born again. A person can hold a recognized position, hear excellent teaching, and gain the confidence of other believers without personally trusting Christ. The people around him cannot see his heart. Neither his title nor his access to the truth can substitute for repentance and faith in Christ.

Jesus was not deceived about Judas. He knew who would betray Him from the beginning, but that knowledge did not make Him the author of Judas’s wrongdoing. We must keep the reality of the appointment together with the responsibility of the man who abused it.

Simon the Cananite, and Judas Iscariot, who also betrayed Him. These twelve Jesus sent out and commanded them, saying: “Do not go into the way of the Gentiles, and do not enter a city of the Samaritans. But go rather to the lost sheep of the house of Israel. And as you go, preach, saying, ‘The kingdom of heaven is at hand.’ Heal the sick, cleanse the lepers, raise the dead, cast out demons. Freely you have received, freely give.

Matthew 10:4-8

Matthew includes Judas among the Twelve sent to announce the kingdom of heaven to the lost sheep of Israel. Jesus gave the group authority over sickness and unclean spirits, and Judas took part in that commission. We are not given an account of a particular miracle he performed, so we should distinguish the authority entrusted to him from details Scripture does not record (Matthew 10:1-8).

His public ministry did not establish that he knew Christ savingly. John records Jesus speaking about unbelief among His followers and then identifying a betrayer within the Twelve.

But there are some of you who do not believe.” For Jesus knew from the beginning who they were who did not believe, and who would betray Him. And He said, “Therefore I have said to you that no one can come to Me unless it has been granted to him by My Father.” From that time many of His disciples went back and walked with Him no more. Then Jesus said to the twelve, “Do you also want to go away?” But Simon Peter answered Him, “Lord, to whom shall we go? You have the words of eternal life. Also we have come to believe and know that You are the Christ, the Son of the living God.” Jesus answered them, “Did I not choose you, the twelve, and one of you is a devil?” He spoke of Judas Iscariot, the son of Simon, for it was he who would betray Him, being one of the twelve.

John 6:64-71

Jesus knew from the beginning who did not believe and who would betray Him. John then identifies Judas as the one Jesus called a devil. I do not understand Judas as a regenerated man who later lost eternal life. The passage exposes unbelief beneath his outward place among the disciples; it never describes him as receiving eternal life and subsequently losing it.

Calling Judas a devil describes his course of opposition to Jesus. It does not turn a human being into a fallen angel or relieve him of responsibility. He remained a man who heard Jesus’ words and refused to believe. The other apostles did not yet recognize the danger, but Jesus did.

The distinction between outward membership and saving faith appears again in Jesus’ prayer on the night before His death. That prayer helps us understand the spiritual condition that Judas’s office could conceal (John 17:6-12).

“For I have given to them the words which You have given Me; and they have received them, and have known surely that I came forth from You; and they have believed that You sent Me. “I pray for them. I do not pray for the world but for those whom You have given Me, for they are Yours. And all Mine are Yours, and Yours are Mine, and I am glorified in them. Now I am no longer in the world, but these are in the world, and I come to You. Holy Father, keep through Your name those whom You have given Me, that they may be one as We are. While I was with them in the world, I kept them in Your name. Those whom You gave Me I have kept; and none of them is lost except the son of perdition, that the Scripture might be fulfilled.”

John 17:8-12

Jesus describes men who received His words and believed that the Father sent Him. The expression “Son of perdition” identifies Judas with destruction. Read alongside John 6, this does not show a born-again person losing salvation. Judas belonged to the apostolic group without sharing the saving relationship Jesus describes in the others.

A true believer is born again, made new, and indwelt and sealed by the Holy Spirit. That security does not make every profession of faith genuine. Churches receive and appoint people on credible evidence because we cannot read hearts without error. Later conduct may expose a profession that never reflected trust in Christ, but one failure does not establish that someone was never saved or that the Spirit’s seal has failed. When I examine myself, I need to ask whether my confidence rests in Jesus and His gospel, without making sinless performance the condition of assurance.

Secret Greed Prepared Judas for Open Betrayal

John explains the dishonesty Judas concealed while holding a trusted position. Earlier, at a supper in Bethany, Mary had honored Jesus with costly perfume, and Judas had objected in words that hid his real interest in the money (John 12:1-8).

But one of His disciples, Judas Iscariot, Simon’s son, who would betray Him, said, “Why was this fragrant oil not sold for three hundred denarii and given to the poor?” This he said, not that he cared for the poor, but because he was a thief, and had the money box; and he used to take what was put in it. But Jesus said, “Let her alone; she has kept this for the day of My burial. For the poor you have with you always, but Me you do not have always.”

John 12:4-8

Judas presented his objection as concern for the poor. John tells us directly that he did not mean it: he was a thief who kept the common money box and used to take what others put into it. The proposed sale would have placed more money within reach of a man already stealing from the fund.

His words sounded charitable, while his conduct betrayed the people who trusted him. John describes repeated theft from entrusted funds, so we are not looking at a single careless transaction. When Judas later bargained for payment to deliver Jesus, his greed was already an established pattern.

Jesus defended Mary and connected her anointing with His burial. He was not dismissing responsibility toward the poor. His public ministry among them was nearing its end, and this act of honor had a particular place in preparing for His burial. Judas heard that explanation while concealing his abuse of the money entrusted to him.

Now as they were eating, He said, “Assuredly, I say to you, one of you will betray Me.” And they were exceedingly sorrowful, and each of them began to say to Him, “Lord, is it I?” He answered and said, “He who dipped his hand with Me in the dish will betray Me. The Son of Man indeed goes just as it is written of Him, but woe to that man by whom the Son of Man is betrayed! It would have been good for that man if he had not been born.” Then Judas, who was betraying Him, answered and said, “Rabbi, is it I?” He said to him, “You have said it.”

Matthew 26:21-25

Judas approached the chief priests, the senior temple authorities who were plotting Jesus’ death, and asked what they would pay him to deliver Jesus. They counted out thirty pieces of silver. From then on, he sought an opportunity to betray Him. The leaders wanted an arrest away from the crowds, and a member of Jesus’ own company could provide the access they needed (Matthew 26:14-25).

Exodus 21:32 gives thirty shekels as compensation when an ox kills a slave. Zechariah 11:12-13 describes thirty pieces of silver as the insulting price assigned to a rejected shepherd. Those passages deepen our understanding of the payment, but Matthew does not identify the precise coins or give enough information to calculate their exact value in modern money.

At Passover, the feast recalling Israel’s deliverance from Egypt, Judas sat among the disciples as Jesus announced the coming betrayal. The others asked, “Lord, is it I?” Judas asked, “Rabbi, is it I?” Jesus pronounced woe on the betrayer and then answered Judas directly. The Son of Man would go as Scripture had foretold, but fulfilling that prophecy did not make Judas’s treachery an act of obedience. John’s account of the supper also shows how little the others understood about Judas.

The Supper and Arrest Reveal Both Satanic Influence and Human Choice

Jesus answered, “It is he to whom I shall give a piece of bread when I have dipped it.” And having dipped the bread, He gave it to Judas Iscariot, the son of Simon. Now after the piece of bread, Satan entered him. Then Jesus said to him, “What you do, do quickly.” But no one at the table knew for what reason He said this to him. For some thought, because Judas had the money box, that Jesus had said to him, “Buy those things we need for the feast,” or that he should give something to the poor. Having received the piece of bread, he then went out immediately. And it was night.

John 13:26-30

Jesus applied Psalm 41:9, which describes betrayal by a table companion. He announced what would happen before Judas carried it out, so the disciples would have further reason to believe who He is when His words came true. The secret plan had never escaped Jesus’ knowledge. The betrayal would fulfill Scripture without excusing the man who chose it (John 13:18-30).

The dipped morsel identified Judas to the disciple asking the question. Sharing food could express fellowship and honor, yet Judas received it from the very hand of the One he had agreed to deliver to His enemies. The other disciples still failed to understand why he left. They thought Jesus might be sending their treasurer to buy supplies or give something to the poor.

Luke 22:3 says Satan entered Judas before he consulted the chief priests. John 13:2 says the devil had already put betrayal into his heart, and John then describes Satan entering him after the morsel. The Gospels present real Satanic influence at these points in his course. They do not say that Judas “sold his soul,” and that familiar expression can obscure what they actually record.

Satan’s activity did not cancel Judas’s choices. Judas had stolen from the fund, negotiated a payment, and looked for an opportunity to deliver Jesus. When Jesus said, “What you do, do quickly,” He allowed Judas to proceed with the course Judas had chosen. He did not command a morally innocent disciple to invent a betrayal. Judas left to carry out the plan, and John closes the scene by telling us it was night. Later, Judas came to Gethsemane with an armed crowd.

And while He was still speaking, behold, Judas, one of the twelve, with a great multitude with swords and clubs, came from the chief priests and elders of the people. Now His betrayer had given them a sign, saying, “Whomever I kiss, He is the One; seize Him.” Immediately he went up to Jesus and said, “Greetings, Rabbi!” and kissed Him. But Jesus said to him, “Friend, why have you come?” Then they came and laid hands on Jesus and took Him.

Matthew 26:47-50

Judas led an armed crowd to Gethsemane, where Jesus had been praying. He had arranged for them to seize the man he kissed, using an outward show of a disciple’s affection to identify his Teacher for arrest. The crowd carrying swords and clubs had been sent by the chief priests and elders.

Jesus called Judas friend while confronting him about why he had come. I do not read that address as a declaration that Judas was spiritually reconciled to Him. The closeness Judas had enjoyed made this use of an affectionate greeting especially brazen. Luke records Jesus naming the betrayal as Judas approached with the kiss.

And while He was still speaking, behold, a multitude; and he who was called Judas, one of the twelve, went before them and drew near to Jesus to kiss Him. But Jesus said to him, “Judas, are you betraying the Son of Man with a kiss?” When those around Him saw what was going to happen, they said to Him, “Lord, shall we strike with the sword?” And one of them struck the servant of the high priest and cut off his right ear. But Jesus answered and said, “Permit even this.” And He touched his ear and healed him. Then Jesus said to the chief priests, captains of the temple, and the elders who had come to Him, “Have you come out, as against a robber, with swords and clubs? When I was with you daily in the temple, you did not try to seize Me. But this is your hour, and the power of darkness.”

Luke 22:47-53

Jesus asked Judas whether he was betraying the Son of Man with a kiss. When one of the disciples struck the high priest’s servant, Jesus stopped the violence and healed the man’s ear. The leaders had seen Him teaching openly in the temple, yet they now came against Him at night as though they were arresting a robber. He exposed their conduct even as He allowed the arrest.

Their hour and the power of darkness did not mean that Judas had forced an unwilling Savior toward the cross. Jesus had already explained that no one took His life from Him; He laid it down Himself. His willing submission would accomplish God’s purpose without making the betrayer or the arresting party innocent.

Judas Felt Remorse but Did Not Turn to Christ

Then Judas, His betrayer, seeing that He had been condemned, was remorseful and brought back the thirty pieces of silver to the chief priests and elders, saying, “I have sinned by betraying innocent blood.” And they said, “What is that to us? You see to it!” Then he threw down the pieces of silver in the temple and departed, and went and hanged himself. But the chief priests took the silver pieces and said, “It is not lawful to put them into the treasury, because they are the price of blood.” And they consulted together and bought with them the potter’s field, to bury strangers in. Therefore that field has been called the Field of Blood to this day. Then was fulfilled what was spoken by Jeremiah the prophet, saying, “And they took the thirty pieces of silver, the value of Him who was priced, whom they of the children of Israel priced, and gave them for the potter’s field, as the LORD directed me.”

Matthew 27:3-10

When Judas saw that Jesus had been condemned, he returned the silver and admitted, “I have sinned by betraying innocent blood.” He acknowledged both Jesus’ innocence and his own guilt. His remorse was real, but acknowledging a wrong and trying to return its proceeds did not by themselves bring him into a saving relationship with Christ.

The Greek verb metamelomai can describe regret or a change of mind, but we cannot infer from that word alone whether someone has turned to God in faith. Thayer’s discussion of the word cautions against drawing an absolute division between this verb and the usual word for repentance. Judas’s recorded response is what we need to examine: he confessed to the men who had paid him, threw the money into the temple, and left. Scripture records no believing return to Jesus. He went and hanged himself.

The priests’ answer was callous: “You see to it.” They had welcomed his help in obtaining Jesus, but they refused responsibility when Judas confronted them with the blood they had purchased. They would not return blood money to the temple treasury, yet had been willing to pay it out to secure the death of an innocent man. Their scruple about the money’s destination did not undo their part in the crime.

The priests bought a potter’s field for burying strangers with the silver Judas returned. Matthew identifies the transaction as fulfilled prophecy and names Jeremiah, although the closest wording appears in Zechariah 11:12-13. Jeremiah 18 and 19 concern a potter and judgment, while Jeremiah 32 records a field purchase, so Matthew may be drawing these prophetic themes together under Jeremiah’s name. I regard that as a possible explanation rather than one Matthew expressly gives. The NET textual notes on Matthew 27:9 explain why Jeremiah should be retained. A difficult reference gives us no reason to replace the prophet’s name.

Judas’s death could not atone for his sin or repair what he had done. I do not understand his condemnation as a declaration that suicide is uniquely unforgivable. His unbelief is established elsewhere in Scripture; we should not assign his whole spiritual condition to every person who dies by suicide. Nor should we burden a grieving family with confident claims about someone’s final moments when God has not revealed them. While a person lives, Christ’s mercy is genuinely offered, and guilt is a reason to turn toward Him and seek help.

Peter’s denial shows why Judas’s end cannot be treated as the inevitable outcome of a believer’s failure. Peter had boasted of his courage, yet he slept in Gethsemane, misused a sword during the arrest, and denied knowing Jesus three times. His own confidence had not kept him faithful. He was a real believer, however, and Jesus had interceded for him.

Peter wept bitterly and later met the risen Christ, who restored him to service. Judas’s remorse did not lead him to that believing dependence. If I fail as a believer, Peter’s restoration gives me reason to confess rather than hide. I need the forgiveness Christ provides and the help of faithful Christians, not an attempt to punish myself enough to pay for my guilt.

Judas’s Vacant Office Was Given to Matthias

Judas’s death left a vacancy among the Twelve. After Jesus’ resurrection and ascension, Peter addressed the gathered disciples about filling it. Acts also supplies details about the field and Judas’s death that we need to read alongside Matthew (Acts 1:15-26).

(Now this man purchased a field with the wages of iniquity; and falling headlong, he burst open in the middle and all his entrails gushed out. And it became known to all those dwelling in Jerusalem; so that field is called in their own language, Akel Dama, that is, Field of Blood.) “For it is written in the Book of Psalms: ‘Let his dwelling place be desolate, And let no one live in it’; and, ‘Let another take his office.’ “Therefore, of these men who have accompanied us all the time that the Lord Jesus went in and out among us, beginning from the baptism of John to that day when He was taken up from us, one of these must become a witness with us of His resurrection.” And they proposed two: Joseph called Barsabas, who was surnamed Justus, and Matthias. And they prayed and said, “You, O Lord, who know the hearts of all, show which of these two You have chosen to take part in this ministry and apostleship from which Judas by transgression fell, that he might go to his own place.” And they cast their lots, and the lot fell on Matthias. And he was numbered with the eleven apostles.

Acts 1:18-26

Matthew identifies the chief priests as the people who bought the field. Acts attributes its acquisition to Judas with the wages of his wrongdoing. I understand Acts to name the man whose money paid for the property, while Matthew identifies those who carried out the transaction. A purchase can be attributed to the person whose funds are used without requiring him to have conducted it personally.

The two books also describe different aspects of Judas’s death. Matthew records his hanging; Acts describes his falling headlong and his body bursting open. A fall after the hanging could account for both descriptions, but neither passage gives the complete sequence. A broken rope or branch is a proposed detail, not something Scripture records. I can recognize a possible reconciliation without claiming to know how or when every physical event occurred.

Matthew says the field became known as the Field of Blood because blood money bought it. Acts gives its Aramaic name, Akel Dama, meaning Field of Blood, while recounting Judas’s notorious death and the property acquired with his wages. The connection with his death does not cancel Matthew’s explanation of how the purchase was funded. Both associations with blood belong to the accounts we have been given.

Peter turned to Scripture to explain why Judas’s office should be filled. He applied Psalm 69:25 to the desolate dwelling and Psalm 109:8 to another man taking Judas’s office. He also identified Judas as the guide for those who arrested Jesus. God knew what would happen, but Judas still acted from corrupt desires under Satanic influence. Fulfilled prophecy did not remove his responsibility for guiding the arresting party to the Lord.

The replacement needed to have accompanied the Lord from John’s baptism through His ascension and to become a witness with the apostles of His resurrection. Joseph Barsabas and Matthias were proposed as men who met those requirements. The believers prayed to the Lord who knows every heart, cast lots, and received Matthias as the man chosen. Acts says he was numbered with the eleven apostles and gives no correction of their action.

For that reason, I find no support for the claim that Peter acted prematurely and should have waited for Paul to become the twelfth. Paul was a genuine apostle, called later by the risen Christ. He had not accompanied Jesus throughout His earthly ministry, as this particular replacement required. Matthias took Judas’s place among the restored Twelve.

Judas Warns the Church and Points Us Back to Christ

Judas warns me against confusing nearness to Christian truth with the new birth. A person can hear sermons, witness answered prayer, work on a ministry team, and gain a respected position without trusting Jesus Christ. We should proclaim the gospel to people inside our churches as well as outside them, rather than assume that a role or long attendance establishes faith.

His theft also gives churches reason to use financial safeguards. A clear budget states how money should be used, receipts allow its use to be accounted for, and independent review helps establish whether those purposes are being honored. One person should not control the entire process without accountability. These practices protect donors, those the ministry serves, and the person entrusted with the funds. They are ordinary stewardship, not an accusation that every treasurer is another Judas.

When a genuine concern arises, it deserves a prompt and fair investigation, with evidence examined rather than rumor or a crowd’s suspicion accepted as a verdict. Biblical qualifications should govern appointments, and truthful evidence should govern correction. Judas’s outward credibility hid theft for a time, giving us reason for accountability without treating every Christian leader as guilty until proved innocent.

Hidden sin needs to be confessed before it becomes a pattern we are determined to protect. Judas repeatedly made room for greed while using respectable words to disguise it. If I am concealing wrongdoing, I need to seek help and accept accountability rather than preserve an appearance of faithfulness. Scripture gives us a serious warning here without requiring speculation about occult transactions.

Remorse over what we have done is not the whole of repentance. Repentance turns from sin toward God and receives His Savior. We cannot pay for guilt by returning enough money, enduring enough shame, or inflicting suffering on ourselves. Judas’s death did not accomplish redemption; Jesus accomplished it through His own willing obedience.

The sinless Son went to Gethsemane knowing what He would face, and He willingly gave Himself to be slain as the perfect sacrifice for our sins. His atonement rests on His perfection and that sacrifice, not on Judas’s treachery or the cruelty of those who crucified Him. Wicked men inflicted real bodily suffering as they tortured and killed Jesus, and He shed His innocent blood and died. His saving sacrifice through His blood and death was complete before His burial. He then rose bodily from the dead. The Father did not punish, curse, abandon, strike, bruise, or pour wrath on Jesus; Father and Son remained united in redemption.

Judas’s rejection of Christ shows the danger of resisting grace, not a defect in the salvation God offers. Christ died for the whole world, making His offer genuine for every person even though people can reject Him. Whoever turns to Jesus in repentance and faith is forgiven and justified, declared righteous before God. God gives that person new birth, and the Holy Spirit comes to dwell within and seal the believer as eternally secure. Obedience gives evidence of that life; it neither earns nor keeps salvation. Such assurance never permits lawlessness, and an empty profession of faith cannot take the place of genuine new birth.

Judas neither created God’s saving purpose nor made his own evil necessary or good. God overruled guilty choices within His promised plan, and Jesus gave Himself willingly. Our confidence belongs in the Savior who accomplished redemption, not in a religious position that may conceal unbelief.

My Final Thoughts

Judas’s appointment did not give him the saving faith he refused, and his remorse could not undo his betrayal. I need to take that warning seriously whenever a religious role begins to seem like proof of my standing before God. Peter’s restoration gives believers ashamed of failure a reason to confess and seek Christ’s help, rather than hide or try to pay for guilt themselves. Jesus was not overcome by Judas or the power of darkness. He willingly gave Himself, rose bodily, and offers mercy to everyone who will repent and believe.
