Brethren, if any of you do err from the truth, and one convert him;
As if he had said, I have now warned you of those sins to which you are most liable; and, in all these respects, watch not only over yourselves, but every one over his brother also. Labour, in particular, to recover those that are fallen.
If any one err from the truth — Practically, by sin.
Be the first to react on this!
