True repentance turns from sin to God, and God responds with mercy when we do. The people of Nineveh demonstrate what it looks like to grieve over sin, turn from wrongdoing, and turn toward God. Their story reminds us that repentance humbles the heart, changes our lives, and even reshapes how we see and treat others. Mercy received calls us to mercy extended—and God’s grace is available to all who turn to Him.
