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

In the nature of sovereign grace theology, salvation is not about the strength of our faith, but about the faith of Christ. Galatians 2:16 emphasizes that a person is not justified by works but through faith in Jesus Christ. When we discuss Christ's faith, we reference His complete and perfect dependence on the Father. As He cried out for deliverance, He exemplified perfect faith in action. This faith is unique, as it is through His faithfulness that we are saved, and not our own. Our salvation is assured because it stands upon the rock of Christ's righteousness rather than our fluctuating believers’ experience. His faith is the source of our faith and the grounds for our acceptance before God’s throne.
