3:7 But when he saw many Pharisees and Sadducees coming to his baptism, he said to them, “You offspring of vipers! Who warned you to flee from the coming wrath? 3:8 Therefore produce fruit that proves your repentance, 3:9 and don’t think you can say to yourselves, ‘We have Abraham as our father.’ For I tell you that God can raise up children for Abraham from these stones! 3:10 Even now the ax is laid at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire.

3:11 “I baptize you with water, for repentance, but the one coming after me is more powerful than I am – I am not worthy to carry his sandals.
