How do we know that Christ is the only hope for salvation?

According to the sermon based on Matthew 8, true faith is recognizing Christ as our only hope. The centurion, in his humble petition, understood that Jesus had sovereign authority over sickness and sin. He demonstrated great faith by asking Jesus to simply speak the word for his servant to be healed. This relationship reveals the necessity of Christ's role in salvation: He alone carries the authority to forgive sins and cleanse us from all unrighteousness. Our salvation is not contingent upon our works or understanding but upon Christ’s completed work on the cross.
