Romans 11:21-23

New Century Version

²¹ If God did not let the natural branches of that tree stay, then he will not let you stay if you don’t believe.

²² So you see that God is kind and also very strict. He punishes those who stop following him. But God is kind to you, if you continue following in his kindness. If you do not, you will be cut off from the tree. ²³ And if the Jews will believe in God again, he will accept them back. God is able to put them back where they were.
