How does God's sovereignty relate to the concept of mercy?

The relationship between God's sovereignty and mercy is foundational in Reformed theology. Romans 9:14-18 illustrates that God's mercy is not based on human criteria or expectations but is granted according to His sovereign will. This underscores the principle that God's grace is entirely His prerogative; He chooses to whom He will show mercy. Understanding this sovereignty reduces human pride and emphasizes the necessity of divine grace in salvation. It reassures believers that their standing before God relies not on their actions, but on God’s sovereign decision to extend mercy.
