Romans 9:15-19

For He says to Moses, “I will have mercy on whomever I have mercy, and I will show compassion to whomever I show compassion.”

So then, it does not depend on the person who wants it nor the one who runs, but on God who has mercy.

For the Scripture says to Pharaoh, “For this very reason I raised you up, in order to demonstrate My power in you, and that My name might be proclaimed throughout the earth.”

So then He has mercy on whom He desires, and He hardens whom He desires.

You will say to me then, “Why does He still find fault? For who has resisted His will?”
