Romans 11:17-24-
11:17 Now if some of the branches were broken off, and you, a wild olive shoot, were grafted in among them and participated in
1 the richness of the olive root,
11:18 do not boast over the branches. But if you boast, remember that you do not support the root, but the root supports you.
11:19 Then you will say, “The branches were broken off so that I could be grafted in.”
11:20 Granted!
2 They were broken off because of their unbelief, but you stand by faith. Do not be arrogant, but fear!
11:21 For if God did not spare the natural branches, perhaps he will not spare you.
11:22 Notice therefore the kindness and harshness of God – harshness toward those who have fallen, but
3 God’s kindness toward you, provided you continue in his kindness;
4 otherwise you also will be cut off.
11:23 And even they – if they do not continue in their unbelief – will be grafted in, for God is able to graft them in again.
11:24 For if you were cut off from what is by nature a wild olive tree, and grafted, contrary to nature, into a cultivated olive tree, how much more will these natural branches be grafted back into their own olive tree?
