In Mormonism, justification is generally understood as being pardoned from sins and brought into alignment with God’s laws. It is closely tied to the process of repentance and obedience. LDS teaching describes justification as conditional — dependent on receiving ordinances, keeping commandments, and enduring to the end. It is not viewed as a once-for-all declaration of righteousness but as something maintained by continued faithfulness.
Biblical Christianity, however, teaches that justification is God’s once-for-all declaration that a sinner is righteous because of Christ’s perfect life and substitutionary death. This happens through faith alone, apart from works of the law (Romans 3:28; Galatians 2:16). Justification is complete and secure, not dependent on human worthiness or ongoing obedience, but on the finished work of Jesus.
