Why is it important to believe in Christ alone for salvation?

The rejection of self-righteousness in favor of faith in Christ is core to Reformed theology, encapsulated in Ephesians 2:8-9, which states that salvation is by grace alone through faith, not by works. This evidences our total dependence on Christ's merit rather than our efforts. The understanding that Christ's obedience and righteousness are imputed to us provides assurance to believers that they stand justified before God, fulfilling the requirement of the law through Him. This belief solidifies the essential truth that salvation is not a human endeavor but a divine gift, reinforcing the centrality of grace in the Christian faith.
