Romans 11:22-24

22So you should think about what God is like. He is kind, but he also punishes people. He has punished Israel's people, because they turned away from him. He has been kind to you. But you must continue to accept his kind gift. If you do not do that, he will break you off from his tree as well.

23God is able to accept Israel's people back again. If they come to believe in Christ, God will put them back as part of the tree. He is able to make them become branches of the tree again.

24God cut you like branches from a wild olive tree. Then he put you into the farmer's olive tree so that you became part of it. He could do that even though that was not your own tree before. So God will be able to do that for Israel's people. He can easily put them back into their own tree, that they were part of before.
