How are Christians justified according to the Bible?

The Bible teaches that justification is a transformative act of God whereby sinners are declared righteous on the basis of faith in Jesus Christ, not by personal merit or works. Romans 3:28 asserts that a person is justified by faith apart from the deeds of the law, underlining the doctrine of grace central to the Christian faith. This means that redemption and acceptance before God are entirely rooted in the finished work of Christ, who fulfilled the law and satisfied divine justice. Consequently, believers are called to place their faith in Christ's righteousness—a perfect righteousness that is credited to them, resulting in a standing of grace before God.
