What does it mean to live by faith in the Son of God?

Living by faith in the Son of God, as referenced in Galatians 2:20, signifies a total dependence on Christ for all aspects of life. This faith is not just initial belief but a continuous act of trust and reliance on Him. It entails acknowledging that our former selves are dead, and we now draw life and sustenance from His grace and righteousness. By living by faith, believers are empowered by the Holy Spirit to produce good works that reflect their new nature—not as a means to earn favor with God, but as a joyful response to His love and sacrifice. This dynamic relationship fosters spiritual growth and assurance as we navigate life's trials.
