Why is understanding grace and mercy important for Christians?

Grace and mercy are central to the Christian faith because they underscore the reality that we cannot earn salvation through our works but must solely rely on Christ's finished work. In the sermon, it is emphasized that our acceptance before God hinges on recognizing this truth. Romans 11:6 clearly states that if salvation is by grace, then it cannot involve works. This understanding liberates believers from the burdens of false religion that insists on self-effort and instead directs them to rest in Christ, who is the fulfillment of all righteousness and the source of their hope.
