Luke 3:3-8

And he went into all the country around the Jordan, preaching a baptism of repentance for the forgiveness of sin; as it is written and forever remains written in the book of the words of Isaiah the prophet, “THE VOICE OF ONE SHOUTING IN THE WILDERNESS, ‘PREPARE THE WAY OF THE LORD, MAKE HIS PATHS STRAIGHT. ‘EVERY RAVINE SHALL BE FILLED UP, AND EVERY MOUNTAIN AND HILL SHALL BE LEVELED; AND THE CROOKED [places] SHALL BE MADE STRAIGHT, AND THE ROUGH ROADS SMOOTH; AND ALL MANKIND SHALL SEE THE SALVATION OF GOD.’ ” [Is 40:3-5] So 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? 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]
