While the people were waiting, questioning in their hearts if John is the Christ, John answered them saying: "I indeed baptize you with water; but One mightier than I is coming, whose sandal strap I am not worthy to loose. He will baptize you with the Holy Spirit and fire. His winnowing fan is in His hand, and He will thoroughly clean out His threshing floor, and gather the wheat into His barn; but the chaff He will burn with unquenchable fire."

Then Jesus came from Galilee to John at the Jordan to be baptized by him. John tried to decline saying: "I have need to be baptized by You, and are You coming to me?" But Jesus answered and said to him: "Permit it to be so now, for thus it is fitting for us to fulfill all righteousness." John accepted and carried out Jesus’ request. When Jesus had been baptized, immediately He came up from the water and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove upon Him. Suddenly a voice came from heaven, saying, "This is My beloved Son, in whom I am well pleased."
