New Defender's Study Bible Notes
1:21 not only in this world. When Christ defeated sin and death and arose from the dead, He ascended far above all heavens (Ephesians 4:10), including all the angelic hosts and their stellar habitations. The risen, glorified Lord Jesus is now King of all creation (Matthew 28:18; Philippians 2:9-11), and will be so forever.
1:23 his body. The theme of the church as the body of Christ, whose members are composed of both Jews and Gentiles, is prominent in Ephesians (2:15-16; 4:4,12-16). See also I Corinthians 12:12-31; Romans 12:4-5; Colossians 1:24.
1:23 fulness of him. This is an amazing concept, that somehow we, the members of His body, can contribute to the “fulness” of the great King who, by virtue of His work of creating, saving and reconciling all things (Colossians 1:16-20) already “fills all things” (Ephesians 4:10; see also 3:19; 4:13; Colossians 2:9-10).
