Luke 3:7–9
7 He said therefore to the multitudes that came out to be baptized by him, “You brood of vipers! Who warned you to flee from the wrath to come? 8 Bear fruits that befit repentance, and do not begin to say to yourselves, ‘We have Abraham as our father’; for I tell you, God is able from these stones to raise up children to Abraham. 9 Even now the axe is laid to the root of the trees; every tree therefore that does not bear good fruit is cut down and thrown into the fire.”
