Why is the doctrine of the imputed righteousness of Christ important for Christians?

Imputed righteousness is foundational for Christians, as it confirms that believers are justified through faith in Christ's sacrificial work on their behalf. According to Romans 4:3, Abraham was justified by faith, highlighting that it is God who credits righteousness apart from works. This doctrine assures believers that their standing before God is not based on their merit but on Christ's perfect obedience and sacrifice. Believing in the imputed righteousness of Christ allows Christians to rest in the sufficiency of His work, providing peace and assurance of salvation, emphasizing the nature of grace as a free gift.
