Romans 9:16-18

16So then, it is God who decides these things. It is not because of what people want. It is not because of what people do. It is because God chooses to be kind.

17The Bible tells us what God said to Pharaoh: ‘This is why I caused you to be king of Egypt. My purpose was to show how powerful I am. As a result, people everywhere would know that I am great.’

18So we see this: God is kind to some people and he forgives them. But he causes some people, like Pharaoh, to turn against him. He chooses what he will do with each person.
