Why is reliance on Christ important for salvation?

Reliance on Christ for salvation is critical because, as outlined in Malachi 3:3, He is the Refiner's fire that purges our self-righteousness and sin. Salvation is not achieved through our own works but through faith in Jesus Christ, who fulfilled the law and paid the penalty for sin. The Gospel assures us that true righteousness comes solely from acknowledging that Christ is our substitute, thus freeing us from the burden of self-justification and allowing us to rest in His finished work.
