“For if I build again the things which I destroyed, I make myself a transgressor.”
King James Version (KJV)
2:18 By no means. For if I build again - By my sinful practice. The things which I destroyed - By my preaching, I only make myself - Or show myself, not Christ, to be a transgressor; the whole blame lies on me, not him or his gospel. As if he had said, The objection were just, if the gospel promised justification to men continuing in sin. But it does not. Therefore if any who profess the gospel do not live according to it, they are sinners, it is certain, but not justified, and so the gospel is clear.
Ga 2:18 If I build again the things which I destroyed. Go back from Christ to Moses, and teach others to do the same. I make myself a transgressor. For thus I teach men to trust in the works of the law which cannot justify.
