There are several passages in the OT and NT that describe the "forgetfulness of God" with respect to our sins:
Isa 43:25 “I, even I, am he who blots out your transgressions, for my own sake, and remembers your sins no more.”
Jer 31:34/Heb 8:12, 10:17 “For I will forgive their wickedness and will remember their sins no more.”...“Their sins and lawless acts I will remember no more.”
Micah 7:19 “You will again have compassion on us; you will tread our sins underfoot and hurl all our iniquities into the depths of the sea.”
Ps 103:12 “as far as the east is from the west, so far has he removed our transgressions from us.”
Many expositors take these statements quite literally, stating that God not only forgives sins, but he literally forgets them as well. As one author put it: "When God forgives... sin he puts it out of his mind; he erases it from the pages of time; he forgets it." Other commentators emphasize the poetic nature of these texts and label them as hyperbole of one kind or another. In general, I think most everyone would agree that these passages indicate God's willingness to "put sins out of His mind", so to speak. It's as if He is saying to repentant sinners, "Don't worry; I won't bring them up again."
However, on the face of it, this seems to contradict the teachings of Paul and others in the NT, such as those in the following verses. So my question is: How can the promises of "forgetfulness" be reconciled with the warnings of future accountability?
2 Cor 5:9-10 "So we make it our goal to please him, whether we are at home in the body or away from it. For we must all appear before the judgment seat of Christ, so that each of us may receive what is due us for the things done while in the body, whether good or bad." [emphasis added]
Rom 14:10,12 "For we will all stand before God’s judgment seat,... each of us will give an account of ourselves to God." (cf Heb. 4:13)
In these warning passages, Paul is clearly addressing repentant sinners (i.e., "Christians"); he is reminding them of their pending appointment with the One Who apparently intends to review all of their actions.
So, which is it: the former passages seem to teach that God "wipes the slate clean", but the latter passages indicate that even Christians will still be accountable for their sins in the future. How can these two teachings be reconciled?
I realize this question could easily be diverted into a doctrinal/theological debate. That is not my intent. Of course a truly omniscient God can't truly forget anything. But that's not the point. I want to understand how these two sets of passages can be "reconciled" from a hermeneutical standpoint.
