Matthew 3:7-10
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.
