Mattityahu (Mat) 3:8-11

If you have really turned from your sins to God, produce fruit that will prove it! And don’t suppose you can comfort yourselves by saying, ‘Avraham is our father’! For I tell you that God can raise up for Avraham sons from these stones! Already the axe is at the root of the trees, ready to strike; every tree that doesn’t produce good fruit will be chopped down and thrown in the fire! It’s true that I am immersing you in water so that you might turn from sin to God; but the one coming after me is more powerful than I — I’m not worthy even to carry his sandals — and he will immerse you in the Ruach HaKodesh and in fire.
