Peter said to them, “Turn to God 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.
Christ sacrificed his life's blood to set us free, which means our sins are now forgiven. Christ did this because of God's gift of undeserved grace to us. God has great wisdom and understanding,
“No longer will they have to teach one another to obey me. I, the Lord, promise that all of them will obey me, ordinary people and rulers alike. I will forgive their sins and forget the evil things they have done.”
God sent Christ to be our sacrifice. Christ offered his life's blood, so by faith in him we could come to God. And God did this to show that in the past he was right to be patient and forgive sinners. This also shows that God is right when he accepts people who have faith in Jesus.
Paul replied, “John baptized people so they would turn to God. But he also told them someone else was coming, and they should put their faith in him. Jesus is the one that John was talking about.”
