3:6 δι’ ἃ ἔρχεται ἡ ὀργὴ τοῦ θεοῦ ἐπὶ τοὺς υἱοὺς τῆς ἀπειθείας·
the edivine retribution was a familiar concept in the ancient worldBut in Israel's religion the fundamental premise of election by the one God provided the key means to resolve the problem of theodicy. God's wrath was directed against Israel itself for its failure to live in accordance with its covenant obligations, not least its lapses into idolatry and immorality, but also against the other nations for failure to recognize Israel as Yahweh's people.
ἔρχεται could denote a wrath already in operation as in Rom.1:18-32.. the wrath takes the form of God giving or allowing his human creatures what they want, leaving them to their own devices.
ἀπειθείας: disobedience (to God)here, as the talk of sexual immorality and idolatry... it is Gentiles who are primarily in mind... such self-projection, such making of self-gratification into an idol, will always be counted by God as disobedience, whether it happens among his own people or beyond the bounds of those who acknowledge him as God, a disobedience whose final end is the destrction of the self.
