3:6 Gentiles are fellow heirs. Although the Old Testament gives occasional glimpses of a unified human race, only in the light of Christ’s sacrifice does God’s plan become clear: in one magnificent act He removed the enmity between Himself and humanity and also took away the divisions that fracture humanity (2:14–18). Paul had reflected before on the unusual way God included Gentiles among His people: contrary to the rules of agriculture, the Gentiles were a wild branch grafted into a cultivated tree (Rom. 11:11–24).
