Luke 3:6

4 As it is written in the book of the words of Isaiah the prophet, “The voice of one crying in the wilderness, ‘Make ready the way of the Lord. Make his paths straight.

5 Every valley will be filled. Every mountain and hill will be brought low. The crooked will become straight, and the rough ways smooth.

6 All flesh will see God’s salvation.’”

7 He said therefore to the multitudes who went out to be baptized by him, “You offspring of vipers, who warned you to flee from the wrath to come?

8 Therefore produce fruits worthy of repentance, and don’t begin to say among yourselves, ‘We have Abraham for our father;’ for I tell you that God is able to raise up children to Abraham from these stones!
