How do we know that Jesus Christ is our only hope of salvation?

In 1 Timothy 2:5, we learn that there is one mediator between God and men, the man Christ Jesus. This reflects the Reformed understanding that salvation comes exclusively through Christ's atoning work on the cross. Noah's faith in God signifies an acknowledgment that Jesus Christ is the fulfillment of God's promise of redemption. According to John 14:6, Jesus asserts, 'I am the way, the truth, and the life. No one comes to the Father except through me,' reinforcing the exclusivity of His role as the hope of salvation.
