How can believers live by the faith of the Son of God?

Galatians 2:20 expresses that believers live 'by the faith of the Son of God, who loved me and gave himself for me.' This means that the believer's existence is sustained not by their own belief but by the faithfulness of Christ and His completed work. It highlights that our faith is ultimately God's gift. We are called to look to Jesus—His promises and character—for strength and guidance, acknowledging that it is His work in us that facilitates our living according to His will. As Christians, we are to cultivate a life of dependence on Christ, recognizing our inability and His sufficiency in every area.
