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

Living by the faith of the Son of God, as indicated by Galatians 2:20, signifies a believer's reliance on Christ's strength and faithfulness. Paul states that he is crucified with Christ, yet he lives, illustrating the transformational effect of Christ's work in a believer’s life. This life reflects trust in Christ’s ability to sustain us both spiritually and in our daily walk. Such a lifestyle involves not striving to meet the law's demands for justification but instead embracing the grace provided through Christ and walking in the liberty that He offers. The faith of the Son of God undergirds our identity and empowers our actions, ensuring that our lives reflect the reality of His salvation.
