Life Is in the Blood: What Does the Bible Mean?

When Scripture says that life is in the blood, it directs our attention to the God who gives life. A creature can bleed to death, but its life was never ours to treat however we pleased. God has the right to tell us how to regard what He has given. From Cain’s murder of Abel to the sacrifices at the tabernacle, the Bible teaches us to recognize His authority over life.

That teaching also prepares us to understand why the New Testament speaks so plainly about the blood of Jesus. He redeemed sinners by willingly shedding His blood and dying for them. We misunderstand His sacrifice if we treat blood as a mysterious power of its own. We also obscure it when our religious language leaves out His actual suffering and death.

Blood Belongs to God Because Life Belongs to Him

Before Scripture records a command about eating blood, it records bloodshed. Cain killed his brother Abel, and God confronted him with the blood crying out from the ground (Genesis 4:10). Abel could no longer answer his murderer, but Cain had not silenced the One who would hold him accountable. God knew whose life had been taken and who had taken it.

Hebrews 12:24 later compares Abel’s blood with the blood of Jesus, which speaks better things. Abel’s murder called for justice against the guilty; Christ willingly gave His life so that guilty people could receive forgiveness. Both passages concern an actual death. The comparison loses its force if we turn either man’s blood into nothing more than a religious image.

After the Flood, God permitted Noah and his family to eat meat, but He placed a restriction on that permission:

"But you shall not eat flesh with its life, that is, its blood."

Genesis 9:4, NKJV

This command came before the law given through Moses and before Israel existed as a nation. God addressed the family from whom the nations would descend. They could receive animals as food, but they could not treat the animal’s blood as ordinary food along with its flesh. The permission to eat meat did not make human beings the owners of life.

Genesis 9 then addresses the shedding of human blood. Human beings bear God’s image, and God requires an accounting for their lives. The passage establishes the seriousness of murder and the judicial responsibility to punish it; it does not authorize private vengeance or excuse the killing of an innocent person. Cain’s crime and God’s words to Noah both confront the assumption that we may dispose of another person’s life simply because we have the strength to do it.

God’s earlier commands had already connected blood with the life He gives and the accountability He requires. Israel’s altar would teach more about atonement without replacing that instruction.

Passover, Covenant, and the Blood on the Altar

In Exodus 12, Israel was still enslaved in Egypt when God announced judgment on the firstborn. He instructed each household to kill an unblemished lamb and put its blood on the doorposts and lintel. He promised to pass over the homes marked by that blood. Israel’s protection rested on God’s provision and promise, not on a claim that every person inside an Israelite home had behaved better than every Egyptian.

The blood on the doorway was not a charm. A lamb had actually died, and God had told the household how to respond to the danger He announced. Trusting Him meant following His instructions. The New Testament brings that provision into clearer focus when John identifies Jesus as the Lamb of God (John 1:29), Paul calls Him our Passover (1 Corinthians 5:7), and Peter describes His precious blood as that of a lamb without blemish or spot (1 Peter 1:18–19). Revelation likewise presents the Lamb who was slain and redeemed people by His blood.

Blood also accompanied the establishment of God’s covenant with Israel. In Exodus 24, Moses read the Book of the Covenant to the people and sprinkled the blood of sacrificed animals. The covenant bound them to the God who had delivered them, and its inauguration involved death. Hebrews 9 returns to that event when explaining Christ’s greater sacrifice. Zechariah 9:11 also connects the release of prisoners with the blood of God’s covenant, in the same chapter that announces the coming King. When Jesus spoke of the new covenant in His blood, He was fulfilling promises already woven through Israel’s Scriptures.

Leviticus explains why God appointed blood for the altar:

"For the life of the flesh is in the blood…"

Leviticus 17:11, NKJV

The verse goes on to say that God gave the blood upon the altar to make atonement for their souls. Atonement is God’s provision for dealing with sin so that sinners may approach Him. The emphasis is on what He gave and commanded. Israel did not discover a spiritual substance that could force an unwilling God to forgive them.

The Hebrew word nephesh, translated as soul in this setting, can refer to life, a living being, or a person, according to context. Here the life of the flesh is identified with its blood, and God appoints the life given in sacrifice to make atonement for the worshiper. The passage explains that provision. It does not establish that human souls possess immortality in themselves or that blood has spiritual power apart from the life God gave.

The command about blood also governed ordinary meals. Moses says in Deuteronomy 12:23 that “the blood is the life.” When an animal was slaughtered for food, its blood was to be poured on the ground like water rather than eaten. Israel could neither consume it at the table nor use it superstitiously to obtain spiritual power. God had specified its use at His altar; His people were to respect His instructions in their homes as well.

At the altar, the different offerings show how carefully Israel was to follow what God commanded. In Leviticus 1, the priests sprinkled the burnt offering’s blood around the altar. Leviticus 4 describes the handling of blood in sin offerings, including its application to the altar’s horns and the pouring out of what remained at its base. Leviticus 5–6 also requires restitution where an offender had defrauded someone or wrongfully withheld what belonged to him. Bringing an offering was no excuse to keep the proceeds of his wrongdoing.

On the Day of Atonement in Leviticus 16, the high priest carried sacrificial blood into the Most Holy Place and sprinkled it at the mercy seat, the cover of the ark where God had appointed him to come. He could not enter whenever he pleased or devise his own terms of approach. One goat was killed and its blood brought within the veil. The high priest confessed Israel’s iniquities over the other goat, which was sent away alive into an uninhabited land. Both goats belonged to the same appointed observance, but they served different purposes. We should not confuse the removal portrayed by the living goat with the shedding of sacrificial blood.

These sacrifices had to be repeated. They taught Israel about sin, death, cleansing, and God’s willingness to receive sinners through the provision He appointed. An animal’s death could not finally remove human guilt. As Paul explains in Hebrews 9–10, the restricted access and recurring offerings pointed beyond that arrangement to Christ. His sacrifice would be sufficient to deal with sin and cleanse the conscience.

Isaiah 53 then directs our attention to the Servant who would bear sins. He is wounded for transgressions, bruised for iniquities, led like a lamb to slaughter, and described as pouring out His soul unto death. The life He gives is His own. Jesus fulfills this through the bodily suffering inflicted on Him by wicked men and through His willing death for sinners. The Father did not strike or bruise His Son. Father and Son were united in providing salvation, while the people who abused and killed Jesus remained responsible for their wickedness.

The Apostles Still Treated Blood as Sacred

With Christ’s sacrifice accomplished, the apostles had to address how Gentile believers should live. In Acts 15, some were demanding circumcision and obedience to the law of Moses as requirements for salvation. The apostles rejected that demand. Gentiles were saved by the grace of the Lord Jesus, just as Jewish believers were, and the church had no authority to place them under a burden God was not imposing.

Nevertheless, the letter sent to the Gentile churches instructed them to abstain from things polluted by idols, sexual immorality, things strangled, and blood. Meat from a strangled animal retained its blood, so those last two instructions belong together. I do not read the prohibition of blood as merely a temporary courtesy toward Jewish dinner guests. God had forbidden its consumption in His instruction to Noah long before Moses, and Acts 15 continues that prohibition among the nations.

This does not restore animal sacrifices or make dietary obedience the basis of justification. A person is not forgiven by keeping blood out of his meals, and he does not have to adopt Israel’s entire ceremonial law to become a Christian. But salvation by grace does not give us permission to dismiss an apostolic command. We can distinguish the means by which God saves us from the obedience He rightly requires of those He saves.

The same apostles who instructed believers to abstain from blood repeatedly taught that Christ redeemed them through His blood. Acts 20:28 says that God purchased the church with His own blood. The Son who became truly human is also truly God; His death was the giving of His own innocent life for His people.

In Romans 3:25, Paul uses hilasterion, a word also used for the mercy seat, to describe God’s provision through Christ and faith in His blood. Propitiation is the theological term for this provision by which God deals with sin and receives the sinner. I do not understand it as the Father transferring His wrath onto Jesus. Romans 5:9 says that believers are justified by Christ’s blood and will be saved from coming wrath through Him. God receives the sinner through the Son’s sacrifice and delivers him from judgment.

Paul develops the results in several letters. Ephesians 1:7 connects redemption through Christ’s blood with the forgiveness of sins, and Ephesians 2:13 says that those once far away have been brought near by His blood. Colossians 1:14 likewise speaks of redemption through His blood and forgiveness; verse 20 describes peace made through the blood of His cross. The blood belongs to the crucified Savior, and these blessings come through what He accomplished in dying for us.

John is equally direct. The blood of Jesus cleanses believers from all sin (1 John 1:7), and Revelation 1:5 describes Him as washing us from our sins in His own blood. In Revelation 5:9, the Lamb is praised because He was slain and redeemed people to God by His blood. The multitude in Revelation 7:14 have washed their robes and made them white in the blood of the Lamb. Their cleansing comes from Him, not from a record of personal innocence.

When Revelation 12:11 describes believers overcoming the accuser by the blood of the Lamb and the word of their testimony, it also says that they did not love their lives to the death. Their confidence rests in Christ even when faithfulness costs them their lives. The verse does not give us a formula for controlling circumstances by repeating words about blood. Christ has redeemed these people, and they confess Him even under the threat of death.

Christ’s Blood and His Finished Sacrifice

Hebrews explains why this sacrifice accomplishes what the earlier offerings could not. The eternal Son became fully human without ceasing to be God, lived without sin, and voluntarily gave Himself to be slain as the perfect sacrifice for sinners. An animal’s death could point toward redemption, but no animal could provide the sinless human life needed in our place. Jesus could, and His sacrifice is sufficient for the whole world.

In Hebrews 9, Paul recalls the high priest entering the inner sanctuary with sacrificial blood. Christ entered once for all through His own blood, having obtained eternal redemption. Animal blood served the outward cleansing God had appointed, but Christ offered Himself without spot to God and cleanses the conscience. We can approach and serve the living God because Christ has dealt with the guilt we could never remove ourselves.

Hebrews 9:18–22 then returns to the inauguration of the covenant through Moses and the cleansing associated with the tabernacle. Within that explanation comes the statement that without the shedding of blood there is no remission, or forgiveness, of sins. Paul is explaining the sacrificial provision that reaches its fulfillment in Christ. Sin is not something God casually overlooks, and we cannot repair our guilt by making a few improvements to our conduct. God provided the sacrifice we needed.

Jesus bore the bodily punishment inflicted by the people who arrested, scourged, and crucified Him. He willingly gave His innocent life for our sins. The Father did not punish, curse, abandon, strike, bruise, or pour wrath on Jesus. Nor did the Son become sinful in His nature or cease to be God. We should be able to explain the horror of the cross without setting the Father against the Son who came to do His will.

Hebrews 10 contrasts the repeated offerings with Christ’s once-for-all offering of His body. His sacrifice does not need to be renewed, and another death is not required when another sinner comes to Him. Believers have confidence to enter God’s presence through His blood because He has accomplished what the old sacrifices anticipated. Our confidence would be badly misplaced if it rested on our ability to add something that His offering lacked.

That welcome makes the warnings in Hebrews all the more serious. Hebrews 10:29 condemns treating the blood of the covenant as common. Hebrews 12:24 speaks of the blood that speaks better things than Abel’s, and Hebrews 13:12 says Jesus sanctified the people with His own blood when He suffered outside the gate. The final chapter calls it the blood of the everlasting covenant (13:20). The book that explains our access to God also confronts contempt for the sacrifice by which He provided it.

Peter calls Christ’s blood precious in contrast to corruptible silver and gold (1 Peter 1:18–19). Money might purchase release from some human obligations, but it cannot purchase our release from sin. Our Redeemer gave His own sinless life. His blood has saving significance because it is His blood, shed in His willing sacrifice; it has no power detached from the Person who gave it.

John 19:34 records blood and water coming from Jesus’ side when a soldier pierced Him after His death. John emphasizes that his testimony is that of an eyewitness. The Son of God had taken on real flesh and blood and had truly died. His sacrifice through His shed blood and death was complete before His burial and bodily resurrection. He did not need further suffering after the cross to finish paying for sin. His resurrection vindicated Him and declared His victory over death. We proclaim the living Savior who actually gave His life for us.

John 6, Communion, and the Response of Faith

Because Jesus spoke about drinking His blood in John 6, some readers wonder how His words can agree with the prohibition of consuming blood. We need to follow the discussion He was having. After He fed the five thousand, the crowd sought Him for more bread. He directed them to the life He gives and explained that those who come to Him and believe in Him receive everlasting life.

As Jesus taught at Capernaum, His words about eating His flesh and drinking His blood offended hearers, and many disciples turned away. Yet He was not telling them to practice cannibalism or violate God’s command about blood. He had already called His hearers to come to Him and believe. His language about eating and drinking describes receiving by faith the life He would give through His death.

I can understand what bread is and still go hungry if I refuse to eat. In the same way, discussing Christ’s sacrifice, admiring His teaching, or agreeing that He was a good man does not amount to trusting Him as Savior. Jesus calls the sinner to depend on Him for life. The imagery of eating and drinking expresses that personal trust; He is not calling His hearers to consume His literal body.

On the night He was betrayed, Jesus gave His disciples bread and a cup during the Passover meal and commanded them to remember Him. Matthew 26:28 records His explanation that His blood of the new covenant is shed for many for the remission of sins. Luke 22:20 also identifies the cup with the new covenant in His blood. The sacrifice anticipated in Israel’s worship was now about to be offered by the One who had come to fulfill it.

The church obeys that command in the Lord’s Supper. Through the bread and cup, we remember the body Christ gave and the blood He shed. They do not become physical flesh and blood, and the meal does not repeat His sacrifice. Paul calls the cup the communion, or fellowship, of Christ’s blood in 1 Corinthians 10:16. Believers share in fellowship around the Savior whose one offering has redeemed them.

That fellowship calls for more than going through a familiar routine. In 1 Corinthians 11, Paul requires believers to examine themselves and warns against careless participation. We should consider our conduct before the Lord whose death we are proclaiming. We also await His return, for the church proclaims His death until He comes (1 Corinthians 11:25–26).

The apostles could therefore command believers to abstain from blood as food while also teaching them to celebrate the Lord’s Supper. There is no conflict between those instructions. In communion, Christians remember and proclaim the death of the Savior they have received by faith. They are not drinking literal blood or offering Christ again.

Neither participating in that meal nor obeying a dietary command can bring about the new birth. God genuinely calls every person to repent and believe in Jesus, and people can resist and reject His call. Those who receive Christ by faith are forgiven and justified, born again as new creations, indwelt by the Holy Spirit, and sealed for the day of redemption. Their security rests in Christ’s finished work, not in an ability to keep themselves saved.

That assurance never grants permission for lawlessness. If I claim Christ’s redemption while treating His commands with contempt, I need to face what my conduct says about that claim. Genuine new birth produces evidence of new life; it does not make a person sinless, and obedience neither earns nor maintains salvation. We obey the Savior who has redeemed us, and we confess our sins rather than defending them.

We can explain the gospel plainly to someone who does not know Christ. The sinless Son gave His body and shed His blood for sinners, truly died, and rose bodily. Forgiveness is offered to everyone who repents and believes in Him. Calling Jesus only an example of love leaves out the sacrifice by which He saves; treating His blood as a charm directs attention away from the Savior. Faith receives Christ Himself and the life He gives.

My Final Thoughts

God’s commands concerning blood teach us to respect the life He gives and to take sin seriously. The sacrifices also teach us that He provided a way for sinners to approach Him, and Christ has fulfilled what those offerings anticipated. His innocent life was given for us, His sacrifice is sufficient, and His work does not need our contribution to make it complete. I can acknowledge the full weight of my guilt without despairing, because the Savior who shed His blood offers real forgiveness. When we gather at His table, we have reason to examine our conduct, thank Him for His mercy, and await His return with confidence in what He has finished.
