How do we know Christ's righteousness is imputed to believers?

The doctrine of imputation is grounded deeply in the biblical narrative, particularly seen in Romans 4:3, where it states that Abraham's faith was counted as righteousness. This establishes the principle that righteousness is not earned but credited to those who believe. Furthermore, 1 John 1:7 affirms that the blood of Jesus cleanses us from all sin, reinforcing the idea that it's not through our merit but through Christ's sacrifice that we gain acceptance before God. The assurance of our standing rests solely on Christ's work, which is evidenced both in Scripture and in the transformative experience of the believer.
