How do we know righteousness imputed is true?

The truth of imputed righteousness is firmly grounded in the biblical testimony provided by Paul in Romans 4. He presents Abraham as an example, highlighting that righteousness was counted to him because of his faith, not due to works. Furthermore, Paul includes David's validation of this doctrine, who declares the blessedness of those whose iniquities are forgiven and whose sins are not imputed (Romans 4:6-8). These scriptural affirmations establish that the imputed righteousness of believers is assured by God's grace and faith in Him.
