Luke 3:7-9

7So he began saying to the crowds who were coming out to be baptized by him, “You brood of vipers, who warned you to flee from the wrath [of God that is] to come?

8Therefore produce fruit that is worthy of [and consistent with your] repentance [that is, live changed lives, turn from sin and seek God and His righteousness]. And do not even begin to say to yourselves [as a defense], ‘We have Abraham for our father [and so our heritage assures us of salvation]’; for I say to you that from these stones God is able to raise up children (descendants) for Abraham [for God can replace the unrepentant, regardless of their heritage, with those who are obedient].

9Even now the axe [of God’s judgment] is swinging toward the root of the trees; so every tree that does not produce good fruit is being cut down and thrown into the fire.”
