Luke 3:7-9

7 Then John said to the crowds coming out to be baptized by him, “You brood of vipers, who warned you to flee from the coming wrath?

8 Produce fruit, then, in keeping with repentance. And do not begin to say to yourselves, ‘We have Abraham as our father.’ For I tell you that out of these stones God can raise up children for Abraham.

9 The axe lies ready at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire.”
