How do we know that God’s grace is sufficient for our salvation?

The sufficiency of God's grace for salvation stems from the doctrine of grace itself, as emphasized in the sermon. The narrative portrays the futility of trying to add to Christ’s atoning work through our efforts or decisions. Biblical passages assert that salvation is not dependent upon human merit but is solely grounded in Christ's finished work on the cross (Ephesians 2:8-9). The comparison of human efforts to the act of digging up a dead king's bones to add humiliation captures the absurdity of trying to enhance what Christ has already completed. Thus, true believers are reminded to rest fully in the completeness of God’s grace, which is the only means by which we stand before Him.
