How do we know salvation depends on Christ and not our faith?

The assurance that salvation is not contingent upon our faith is deeply rooted in the Gospel. In the case of the father who brought his son to Jesus, his belief was frail. Nevertheless, Jesus healed the boy, demonstrating that it is not the magnitude of our faith, but the grace and authority of the Savior that effects salvation. The Bible clearly supports that God's mercy is granted based on Christ's atoning work alone—this is a cornerstone of Reformed theology, emphasizing that our trust in Christ is based on his sufficient sacrifice and power.
