Why is understanding justification important for Christians?

Justification before God is fundamental to the Christian faith because it denotes that believers are declared righteous based on Christ's atoning work. This key doctrine assures Christians that they are forgiven of all sins, rooted in the justice of God that requires that forgiveness to be based on a just ground—the blood of Jesus Christ (Romans 3:25). Not only does it provide assurance of forgiveness, but it also establishes a believer's identity in Christ, as they are viewed through the lens of His righteousness, which leads to a life transformed by grace. This understanding fosters confidence and peace, encouraging Christians to live in obedience and worship.
