Romans 11:20-22 New Life Version (NLV)
20 It is true. They were broken off because they did not put their trust in Christ. And you are there only because of your faith. Do not be proud. Instead, be afraid. 21 God did not keep the first branches (who are the Jews) on the tree. Then watch, or He will not keep you on the tree. 22 We see how kind God is. It shows how hard He is also. He is hard on those who fall away. But He is kind to you if you keep on trusting Him. If you do not, He will cut you off.
