Luke 3:7-9

7Therefore John was saying to the crowds that came out to be immersed by him, “You brood of vipers! Who warned you to flee from the coming wrath?

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

9Even now the axe is laid at the root of the trees, so every tree that does not produce good fruit is cut down and thrown into the fire!”
