Why is grace and mercy significant in the Christian life?

Grace and mercy are defining characteristics of the Christian faith. Without them, there can be no true understanding of our salvation. In Romans 9, Paul highlights God's sovereignty, explaining that He chooses to show mercy to whom He wills. This reinforces the concept that our relationship with God is based not on our own actions but solely on His grace. Recognizing the weight of our sin and the depth of God's mercy compels us to serve Him faithfully, as we grasp the reality that we are sustained and empowered by His grace in every aspect of our lives.
