21for if God didn’t spare the natural branches, neither will he spare you.
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.
