“And think not to say within yourselves, ‘We have Abraham to our father:’ for I say unto you, that God is able of these stones to raise up children unto Abraham.  And now also the axe is laid unto the root of the trees: therefore every tree which bringeth not forth good fruit is hewn down, and cast into the fire.  I indeed baptize you with water unto repentance: but He that cometh after me is mightier than I, whose shoes I am not worthy to bear: He shall baptize you with the Holy Ghost, and with fire: whose fan is in His hand, and He will throughly purge His floor, and gather His wheat into the garner; but He will burn up the chaff with unquenchable fire.”
Matthew 3:9-2
