How do we know that Jesus' way to eternal life is true?

The truth of Jesus' path to eternal life is rooted in His unique nature and His fulfillment of the law. As stated in Romans 10:3-4, Christ is the end of the law for righteousness to everyone who believes. Unlike anyone else, Jesus perfectly obeyed the law (John 8:46) and laid down His life for sinners, demonstrating love and mercy. His resurrection confirms His victory over sin and death, proving that He alone is able to give eternal life to those who believe on Him (John 3:16). This assurance calls believers to trust not in their works but in Christ’s finished work on the cross.
