Luke 3:8

Therefore 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]. [Matt 3:9]
