And He will say [i.e., the Lord is represented as saying this in the judgment. See Matt. 7:23; 8:11- 12], ‘I tell you, I do not know where you came from, [so] go away from me, all you people who have done sinful things.’
Demonstrate by your lives that you have [really] repented, and quit saying to yourselves, ‘We claim Abraham as our forefather,’ because I tell you, God is able to make Abraham’s children out of these stones.
These people claim to know God [as Savior], but they deny Him by their actions, so they are detestable and disobedient and unfit for doing anything good.
