Why is living by faith in the Son of God important?

In Galatians 2:20, the Apostle Paul emphasizes that he lives 'by the faith of the Son of God,' signifying that our entire spiritual existence is intertwined with Christ’s faithfulness. This faith is not merely intellectual assent but a deep, abiding trust in who Christ is and what He has accomplished. By relying on His faith, we can navigate life’s challenges, grow in grace, and produce fruit that honors God. Additionally, this faith helps us remain anchored in the gospel, preventing the pitfalls of self-righteousness and despair that can arise when we attempt to live by our own strength.
