Romans 11:21-22

21God broke off the proper branches and he did not let them stay in the tree. So, if you no longer trust him, he will not let you stay either.

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.
