How do we know the faith of Jesus Christ is true?

The faith of Jesus Christ is affirmed by His actions and fulfillment of scripture throughout His life. Hebrews 12:2 describes Jesus as the author and finisher of our faith, demonstrating that He not only initiates faith but perfects it through His work. His sacrifice is a testament to His faithfulness, achieving our redemption by being made a curse for us, as stated in Galatians 3:13. This act of complete obedience validates the integrity of His faith and provides a basis for our faith to rest upon His righteousness, not our own.
