Pentecost, or Feast of Weeks, was celebrated seven weeks after Passover. It was one of the three annual pilgrimage feasts where Jews from all over the world made the trek to Jerusalem to celebrate. They were celebrating the first fruits of their crops and would offer up some of the crops as a way to thank God our Father.
Jesus was crucified on the Passover, fifty days before Pentecost. During Pentecost, Jerusalem was packed with people. The disciples were gathered together in one place and the Spirit descended on them, entering like a mighty rushing wind and descending like dividing tongues as of fire, resting on each one. God’s Spirit was given as a sort of “first fruits” to the Christians that day.
As the Feast of Weeks was a celebration of plentiful harvest, so the ushering in of God’s Spirit commemorate a plentiful harvest of souls. Disciples began speaking in different languages, so that everyone could hear the message in their native tongue. Peter preached a sermon on the resurrection of Jesus, a fitting message for the celebration of the new crop. Peter said, “God raised him up, loosing the pangs of death, because it was not possible for him to be held by it” (Acts 2:24 ESV).
Peter delivered the rest of his message, which cut the people to the heart and prompted their question, “What shall we do?” Peter replied, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself” (Acts 2:38, 39).
Luke says that those who received his word were baptized, and about three thousand were added to the church that day. This is the Good News for those of us who were once dead in our sins. There is a first fruit of the Spirit that waits for us, which will renew us and give us power over death. There was revival on the day of Pentecost!
