Romans 11:29-32

God never changes his mind about the people he calls and the things he gives them. At one time you refused to obey God. But now you have received mercy, because those people refused to obey. And now the Jews refuse to obey, because God showed mercy to you. But this happened so that they also can receive mercy from him. God has given all people over to their stubborn ways so that he can show mercy to all.
