Pentecost, originally a Jewish feast known as the Feast of Weeks (Leviticus 23:15-21), became the day on which God poured out the Holy Spirit on the followers of Jesus, marking the birth of the Church. This occurred fifty days after the resurrection of Christ, as the disciples waited in obedience for the promise of the Father.
Acts 2:1-2 says, “When the Day of Pentecost had fully come… suddenly there came a sound from heaven, as of a rushing mighty wind.” The Holy Spirit filled the house, and tongues of fire appeared over each person. They began to speak in other languages as the Spirit gave utterance, declaring the wonderful works of God (Acts 2:4,11).
Jews from every nation who had come to Jerusalem heard the disciples speaking in their own languages. Peter stood up and preached that this event fulfilled the prophecy of Joel 2:28-32, where God said He would pour out His Spirit on all flesh.
Peter boldly proclaimed Jesus as the crucified and risen Lord. Acts 2:36-37 records, “Let all the house of Israel know assuredly that God has made this Jesus… both Lord and Christ.” The people were cut to the heart, and about 3,000 souls were added that day (Acts 2:41).
Pentecost marks the outpouring of the Spirit, the beginning of gospel proclamation to the nations, and the empowering of believers to be witnesses of Christ. Acts 1:8 had promised this power, and Pentecost fulfilled it.
This day signifies the transition from the old covenant to the new, from law to Spirit, and from isolation to worldwide mission.
