In context
Before · Romans 11:19–20
19You will say then, “Branches were broken off, that I might be grafted in.” 20True; by their unbelief they were broken off, and you stand by your faith. Don’t be conceited, but fear;
21for if God didn’t spare the natural branches, neither will he spare you.
After · Romans 11:22–23
22See then the goodness and severity of God. Toward those who fell, severity; but toward you, goodness, if you continue in his goodness; otherwise you also will be cut off. 23They also, if they don’t continue in their unbelief, will be grafted in, for God is able to graft them in again.
