You brood of vipers! Who warned you to flee from the wrath to come. … Even now the ax lies at the root of the trees. Therefore every tree that does not bear good fruit will be cut down and thrown into the fire. I am baptizing you with water, for repentance, but the one who is coming after me is mightier than I. I am not worthy to carry his sandals. He will baptize you with the Holy Spirit and fire.
