6 just as David also describes the blessedness of the man to whom God imputes righteousness apart from works: 7 “Blessed are those whose lawless deeds are forgiven, and whose sins are covered; 8 Blessed is the man to whom the Lord shall not impute sin.” (Romans 4:6–8, NKJV)
Abraham was not the only person justified by faith. Truly, everyone who is justified will be justified by faith, not by works of law. The reason is clear – “all have sinned” (Rom. 3:23). Importantly, it was Abraham’s faith that was accounted to him for righteousness (Rom. 4:3). The same is true of every soul who is justified by faith – “his faith is accounted to him for righteousness” (Rom. 4:5). David supported this vital truth in Psalms 32:1-2, which Paul now quotes (v. 7-8). The Lord does not charge the account of the sinner who is justified by faith. Instead, God accounts that person’s faith for righteousness. (Remember, saving faith is includes obedience to God – the works of faith. It is this complete or “perfect” faith that justifies the sinner, Jas. 2:20-24.) This verse does not say the righteousness of Christ is imputed to the sinner. It supports the truth of Genesis 15:6 that is quoted in Romans 4:3, “Abraham believed God, and it (Abraham’s faith, jrp) was accounted to him for righteousness.” When we have the type of faith Abraham and David had, our sins are forgiven because our faith (like theirs) is imputed to us (put to our account) for righteousness.
