18 do not boast against the branches. If you do boast, consider that you do not support the root; the root supports you.
19 Indeed you will say, “Branches were broken off so that I might be grafted in.”
20 That is so. They were broken off because of unbelief, but you are there because of faith. So do not become haughty, but stand in awe.
21 For if God did not spare the natural branches, [perhaps] he will not spare you either.
22 See, then, the kindness and severity of God: severity toward those who fell, but God’s kindness to you, provided you remain in his kindness; otherwise you too will be cut off.
23 And they also, if they do not remain in unbelief, will be grafted in, for God is able to graft them in again.
24 For if you were cut from what is by nature a wild olive tree, and grafted, contrary to nature, into a cultivated one, how much more will they who belong to it by nature be grafted back into their own olive tree.
