Romans 11:22-24

22Behold then the kindness and severity of God; to those who fell, severity, but to you, God’s 1kindness, 2if you continue in His kindness; otherwise you also 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 were grafted contrary to nature into a cultivated olive tree, how much more will these who are the natural branches be grafted into their own olive tree?
