Baptism

10 The ax is already at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire.

11 I baptize you with water for repentance. But after me will come one who is more powerful than I, whose sandals I am not fit to carry. He will baptize you with the Holy Spirit and with fire.

12 His winnowing fork is in his hand, and he will clear his threshing floor, gathering his wheat into the barn and burning up the chaff with unquenchable fire.

-- Matthew 3:10-12
