they were pierced to the heart, and said to Peter and the rest of the apostles, Brethren, what shall we do? And Peter
said to them, ‘Repent, and let each of you be baptized in the name of Jesus Christ for the forgiveness of your sins and you shall receive the gift of the Holy Spirit.'” In this passage Peter had just finished preaching the gospel of Jesus to a large number of Jews that had come to Jerusalem to celebrate the Pentecost. They were now convinced that they had crucified Jesus, the one God had sent to them. Peter explained to them that to receive God’s forgiveness and His Holy Spirit, they must repent and be baptized. The Greek word “kai” is a conjunction and is translated “and,” indicating that both repentance and baptism were equally part of this command in order to receive forgiveness of sins.
