Justification and regeneration are closely related doctrines. Regeneration occurs in believers' hearts when they receive Christ and become “born again.” It refers to an impartation of life and is God’s answer to the problem of sin and spiritual death. In comparison, justification by faith is the foundational truth of God’s provision of salvation. Justification is often misunderstood but is one of the profound truths of God’s salvific plan restored to the church from the Protestant Reformation.
