Why is the doctrine of justification important for Christians?

Justification is a pivotal doctrine within Christianity that emphasizes how believers are made right with God. As articulated in Romans 5:1, being justified through faith gives believers peace with God, marking the beginning of a new relationship with Him. The Reformed tradition teaches that justification is by grace alone, reinforcing that it is not based on human merit but entirely on Christ's righteousness. This doctrine also combats legalism by affirming that no works can contribute to salvation; rather, it is through faith in Christ—a truth Spurgeon ardently preached. This understanding frees believers from the bondage of works righteousness and instills a deep appreciation for God's unmerited favor.
