18 do not glorify yourself above the branches. For though you glory, you do not support the root, but the root supports you.
19 Therefore, you would say: The branches were broken off, so that I might be grafted on.
20 Well enough. They were broken off because of unbelief. But you stand on faith. So do not choose to savor what is exalted, but instead be afraid.
21 For if God has not spared the natural branches, perhaps also he might not spare you.
22 So then, notice the goodness and the severity of God. Certainly, toward those who have fallen, there is severity; but toward you, there is the goodness of God, if you remain in goodness. Otherwise, you also will be cut off.
23 Moreover, if they do not remain in unbelief, they will be grafted on. For God is able to graft them on again.
24 So if you have been cut off from the wild olive tree, which is natural to you, and, contrary to nature, you are grafted on to the good olive tree, how much more shall those who are the natural branches be grafted on to their own olive tree?
