Luke 3:3-8

And he came into all the region round about the Jordan, preaching the baptism of repentance unto remission of sins; as it is written in the book of the words of Isaiah the prophet, The voice of one crying in the wilderness, Make ye ready the way of the Lord, Make his paths straight. Every valley shall be filled, And every mountain and hill shall be brought low; And the crooked shall become straight, And the rough ways smooth; And all flesh shall see the salvation of God. He said therefore to the multitudes that went out to be baptized of him, Ye offspring of vipers, who warned you to flee from the wrath to come? Bring forth therefore fruits worthy of repentance, and begin 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.
