THERE is something very remarkable about what is written of "One God and Father of all," in Eph. 4:66One God and Father of all, who is above all, and through all, and in you all. (Ephesians 4:6). (1) " Who is over all, and (2) through all, and (3) in all." I compare it with 1 Cor. 15:2424Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power. (1 Corinthians 15:24); "To God and Father," i.e.,” to (Him who is) God and Father." It is very obvious that in 1 Cor. 15:2424Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power. (1 Corinthians 15:24), it is " God and Father " (of all), as in Eph. 4:66One God and Father of all, who is above all, and through all, and in you all. (Ephesians 4:6)—" One God and Father of all." It is not in either place the Father of Christians (though the same Person who is so), but the first Person of the Trinity that is designated Father..It is not in His relationship in Christ to us, but in His mode of existence. It is God the Father in His creatorial, providential, and all-pervading nature who is spoken of. He is no doubt all this to Christians, but there is their added relationship to Him as God and Father in Christ: "My Father and your Father my God and your God " (also see Eph. 1:3-63Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly places in Christ: 4According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: 5Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, 6To the praise of the glory of his grace, wherein he hath made us accepted in the beloved. (Ephesians 1:3‑6)).
“In all " (Eph. 4:66One God and Father of all, who is above all, and through all, and in you all. (Ephesians 4:6)) is the true reading: not " in you all," which was the mere gloss of acknowledge, and because they did not see that it was " God and Father of all " in universal sovereignty as having all in His possession. They thought it must refer to the Church. But it is true that He who is God and Father of the universe, is He who in Christ Jesus is the Father of all who believe in the Son of God, and have the son standing.
This (v. 6) is God and the universe, and shows the all-comprehending sweep and magnitude of that into which we have been brought in Christ Jesus.
The unity is threefold.
(1) One Spirit and one Body.
(2)One Lord and one Christendom.
(3)One God, who is Father of all, and One Universe.
