21 For, if God did not spare the natural branches, neither will he spare you.
22 See, then, both the goodness and the severity of God — his severity towards those who fell, and his goodness towards you, provided that you continue to confide in that goodness; otherwise you, also, will be cut off.
23 And they, too, if they do not continue in their unbelief, will be grafted in; for God has it in his power to graft them in again.
