3:16 he. The prayer offered by Paul in Ephesians 3:16-19 is addressed to the Father (Ephesians 3:14) and concerns the indwelling of Christ by faith (Ephesians 3:17) and inner strengthening by the Holy Spirit (Ephesians 3:16). Thus all three Persons of the Godhead dwell in the heart of the believer (see also John 14:16-17,23), so that we can “be filled with all the fulness of God” (Ephesians 3:19).

3:16 strengthened. “Strengthened” in this verse is the same as “able” (or, better, “fully able”) in Ephesians 3:18.
