Having foreordained us (Προορισας ημας). First aorist active participle of προοριζω, late and rare compound to define or decide beforehand. Already in Acts 4:28; 1. Corinthians 2:7; Romans 8:29. See also verse Ephesians 1:11. Only other N.T. example in verse Ephesians 1:11. To be taken with εξελεξατο either simultaneous or antecedent (causal).

Unto adoption as sons (εις υιοθεσιαν). For this interesting word see Galatians 4:5; Romans 8:15; Romans 9:4.

Unto himself (εις αυτον). Unto God.

According to the good pleasure of his will (κατα την ευδοκιαν του θεληματος αυτου). Here ευδοκιαν means

purpose like βουλην in verse Ephesians 1:11 rather than

benevolence (good pleasure). Note the preposition κατα here for standard.
