How do we know Christ's faith is significant for our salvation?

Christ's faith holds paramount significance in the context of salvation because, as stated in Galatians 2:15-16, we are justified by His faith rather than our own. The faith of Christ is described as eternal and perfectly fulfilled through His life and actions. This is further supported in Hebrews 2:17, which indicates that it was essential for Christ to be made like us in every way, enabling Him to function as a merciful and faithful high priest. His obedience, sacrifice, and faithfulness throughout His life allow believers to be assured of their standing before God, rooted not in fluctuating human faith but in the unwavering faith of Christ.
