What is the role of Christ in a believer's salvation?

In Christian doctrine, Jesus Christ is regarded as the only mediator between God and man (1 Timothy 2:5). His perfect righteousness is credited to believers, ensuring that they are justified before God. The concept of Christ as the sinner's substitute emphasizes that He bore the penalty for sin and achieved a perfect righteousness through His obedience and sacrificial death. Therefore, all benefits of salvation are accessed through faith in Him, who acts as our Prophet, Priest, and King, guiding and sustaining the believer in their walk of faith.
