This is God doing what we cannot do ourselves. This is righteousness by faith. What the law could not do, because it was weak through the flesh (Rom. 8:3), God does through the Holy Spirit, writing His law in the hearts of believers, so that Christ really lives in them by faith, and His will is their will. Then we know God as the God of grace, passing by our transgressions, separating our sins from us as far as the east is from the west, hiding them behind His back, and blotting them out as a thick cloud. He forgives our iniquities, for it is written, "If we confess our sins, he is faithful and just to forgive us our sins, and cleanse us from all unrighteousness" (1 John 1:9).
Not only so, but the promise goes further still: "I will remember their sin no more." Can God forget? He says He will forget our sins, and He means what He says. So the Lord completely obliterates the iniquity of His people. This is God's act of oblivion. This is the forgiving Father receiving back into His home and into His heart the prodigal child. When God forgives, He forgets. Why? Because "Christ died for our sins according to the scriptures" (1 Cor. 15:3).
Forgiven, forgiven, all cleansed in the blood,
My sins are remembered no more;
Atoned for by Jesus in Calvary's flood,
My sins are remembered no more.
MEDITATION PRAYER: "Hide thy face from my sins, and blot out all mine iniquities" (Ps. 51:9).
