Matthew Henry's Concise Commentary

18:21-29 The wicked man would be saved, if he turned from his evil ways. The true penitent is a true believer. None of his former transgressions shall be mentioned unto him, but in the righteousness which he has done, as the fruit of faith and the effect of conversion, he shall surely live. The question is not whether the truly righteous ever become apostates. It is certain that many who for a time were thought to be righteous, do so, while ver. 26,27 speaks the fulness of pardoning mercy: when sin is forgiven, it is blotted out, it is remembered no more. In their righteousness they shall live; not for their righteousness, as if that were an atonement for their sins, but in their righteousness, which is one of the blessings purchased by the Mediator. What encouragement a repenting, returning sinner has to hope for pardon and life according to this promise! In verse 28 is the beginning and progress of repentance. True believers watch and pray, and continue to the end, and they are saved. In all our disputes with God, he is in the right, and we are in the wrong.
