How do we know that God makes us to differ?

In Exodus 11:7, God Himself proclaims that He places a distinction between the Egyptians and Israel, indicating His sovereign choice. Likewise, Romans 9 clarifies that it is not based on human will or effort, but rather God’s mercy that makes individuals differ. Verse 15 states, 'I will have mercy on whom I will have mercy,' illustrating that God's sovereign decision is central to our salvation and difference in status before Him. This understanding diminishes human pride and acknowledges God's sovereign grace.
