Matthew 3:11-12

Truly, I give baptism with water to those of you whose hearts are changed; but he who comes after me is greater than I, whose shoes I am not good enough to take up: he will give you baptism with the Holy Spirit and with fire: In whose hand is the instrument with which he will make clean his grain; he will put the good grain in his store, but the waste will be burned up in the fire which will never be put out.
