Romans 11:22-24

New Catholic Bible

²² Therefore, keep in mind the kindness and the severity of God: his severity toward those who fell, but his kindness to you provided that you remain deserving of that kindness. Otherwise, you also will be cut off, ²³ while those who do not persist in their unbelief will be grafted in, since God has the power to do so again. ²⁴ For if you have been cut from what is by nature a wild olive tree and grafted contrary to nature into a cultivated one, how much more easily will these natural branches be grafted back into their own olive tree.
