How do we know the faith of Christ is true?

Scripture provides clarity on the authenticity of the faith of Christ. Galatians 2:16 teaches that we are justified by the faith of Jesus Christ, not by the works of the law, reinforcing that our salvation relies entirely on Christ's obedience and faithfulness. This faith is a gift from God, as Ephesians 2:8 reminds us, stating that we are saved by grace through faith, which is not of ourselves. It is a divine gift, underscoring the truthfulness and reliability of the faith we place in Christ.
