Why is imputed righteousness important for salvation?

Imputed righteousness is critical for salvation as it pertains to how God justifies sinners. In Romans 1:17, Paul states that in the gospel, the righteousness of God is revealed. This righteousness is not based on the believer's works but rather on the obedience of Christ, which is counted as righteousness for those who believe. Romans 4 elaborates on this concept, explaining that faith in God is credited as righteousness. Thus, imputed righteousness allows believers to be declared righteous before a holy God, fulfilling the requirements of His law and justice.
