Romans 11:22-24

22See then the kindness and severity of God: to those who fell, severity, but to you, God’s 1kindness, 2if you continue in His kindness; for otherwise you too 3will be cut off. 23And they also, 4if 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 contrary to nature were grafted into a cultivated olive tree, how much more will these who are the natural branches be grafted into their own olive tree?
