Romans 11:18-20
11:18 do not boast over the branches. But if you boast, remember that you do not support the root, but the root supports you.
11:19 Then you will say, “The branches were broken off so that I could be grafted in.”
11:20 Granted! They were broken off because of their unbelief, but you stand by faith. Do not be arrogant, but fear!
