What does Romans 4:7-8 teach about the forgiveness of sins?

In Romans 4:7-8, Paul quotes David to remind us of the profound blessing that comes from God's forgiveness. The verses affirm that those whose iniquities are forgiven and whose sins are covered are blessed because the Lord will not impute sin to them. This assurance of forgiveness reflects the core message of sovereign grace theology: that salvation is not based on our righteousness but is rooted in God's gracious act of imputation—where Christ's righteousness is counted to believers, freeing them from the penalty of sin.
