22 Therefore consider the goodness and severity of God: on those who fell, severity; but toward you, goodness, if you continue in His goodness. Otherwise you also will be cut off. 23 And they also, if they do not continue in unbelief, will be grafted in, for God is able to graft them in again.” (Romans 11:22–23, NKJV)
In considering the purposes of God that brought Gentiles into His kingdom while at the same rejecting unfaithful Jews, it is imperative that we recall God’s goodness and His severity. His goodness leads us to repentance (Rom. 2:4). So does His severity (Heb. 10:26-31). It is altogether proper to use God’s punishment of sin as an incentive to be faithful to Him, because our God is a “consuming fire” against transgressors (Heb. 12:29). This verse tolls the death knell for the doctrine of the impossibility of apostasy. Those who do not “continue in His goodness” do not remain in His favor (“the soul who sins shall die,” Ezek. 18:20). God’s severity is impartially meted out against those who do evil (Rom. 2:9-11). God goodness is extended to and received by all who will “fear God and keep His commandments,” including Jews who “do not continue in unbelief” (Rom. 11:23). If Paul can use the goodness and the severity of God to urge people to follow Jesus, then we are confident we can, and should, do the same.
