Romans 11:
17But if some of the branches were broken off, and you, being a wild olive, were grafted in among them and became partaker with them of the rich root of the olive tree,
18do not be arrogant toward the branches; but if you are arrogant,
remember that it is not you who supports the root, but the root
supports you.
19You will say then, “Branches were broken off so that I might be grafted in.”
20Quite right,
they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear;
21for if God did not spare the natural branches, neither will He spare you.
22Behold then the kindness and severity of God; to those who fell, severity, but to you, God’s kindness, if you continue in His kindness; otherwise you also will be cut off.
23And they also,
if they do not continue in their unbelief, will be grafted in; for God is able to graft them in again.
24For if you were cut off from what is by nature a wild olive tree, and were grafted contrary to nature into a cultivated olive tree, how much more shall these who are the natural
branches be grafted into their own olive tree?
