Why is Christ's role as judge important?

Romans 2:16 indicates that 'in the day when God shall judge the secrets of men by Jesus Christ according to my gospel.' This affirms that Christ is appointed as the judge who will evaluate the faith of every individual. His role is crucial because it assures believers that justice will be served and grace will be applied to those who trust in Him. It also highlights that our standing before God is determined by our relationship with Christ, emphasizing the necessity of having faith in Him as both Lord and Savior.
