John 1:29
The very next day John saw Jesus coming toward him and yelled out, “Here he is, God’s Passover Lamb! He forgives the sins of the world! This is the man I’ve been talking about, ‘the One who comes after me but is really ahead of me.’ I knew nothing about who he was—only this: that my task has been to get Israel ready to recognize him as the God-Revealer. That is why I came here baptizing with water, giving you a good bath and scrubbing sins from your life so you can get a fresh start with God.”
John 1:29-31
