ANSWER: There were two kinds of forgiveness, pretermission, passing over, by withholding penalty, as in Rom. 3:25, R V., and remission, letting sins go, as if they had not been committed, i. e., they are pardoned. The two Greek words are paresis and aphesis. In the former case the efficacy of the atonement is reflected back upon the sins of the truly penitent sinners of previous ages, who trusted in the mercy of God.
