Why is God's grace significant in the context of judgment?

God's grace is the unmerited favor that He shows to His elect, even amid judgment on the reprobate. In Exodus, amidst the plagues affecting Egypt, the distinction is made between God’s people and others, demonstrating His mercy. For example, during the plagues, the Israelites in Goshen were spared from the devastation that befell Egypt. This relationship points to a deeper spiritual truth: that God's grace is not simply about temporary relief but about His sovereign choice to save a people for Himself, ensuring that they are preserved through judgment and ultimately saved.
