What does the Bible say about the doctrine of imputation?

The doctrine of imputation is fundamentally important within Scripture, specifically concerning how sin and righteousness are attributed to individuals. Romans chapter 4 emphasizes that righteousness is attributed 'without works' and rooted in faith. When Adam sinned, sin and guilt were imputed to all humanity (Romans 5:12), making all people guilty before God. This sets the stage for the necessity of Christ's sacrificial act, where the sins of the elect are imputed to Jesus at Calvary (1 Peter 3:18). Furthermore, the righteousness of Christ is imputed to believers by faith, affirming that salvation is a gift of grace, not achieved by our works but by Christ's righteous obedience.
