God has a “mysterious plan” that He is accomplishing and bringing about in Christ Jesus. This plan, though hidden for ages in God, has come to light and is to be made known to the world.

In this expositional study of Ephesians 3:9, Nathan Johnson examines Paul’s declaration and explains not only what the mystery is but how we as Christians are supposed to showcase it every day of our lives.

Key Passage: Ephesians 3:9

Ephesians 3:8-13 – To me, the very least of all saints, this grace was given, to preach to the Gentiles the unfathomable riches of Christ, and to bring to light what is the administration [plan] of the mystery which for ages has been hidden in God who created all things; so that the manifold wisdom of God might now be made known through the church to the rulers and the authorities in the heavenly places. This was in accordance with the eternal purpose which He carried out in Christ Jesus our Lord, in whom we have boldness and confident access through faith in Him. Therefore I ask you not to lose heart at my tribulations on your behalf, for they are your glory.

The Mystery

  • Ephesians 3:3–5 – that by revelation there was made known to me the mystery, as I wrote before in brief. By referring to this, when you read you can understand my insight into the mystery of Christ, which in other generations was not made known to the sons of men, as it has now been revealed to His holy apostles and prophets in [by] the Spirit …
  • Ephesians 5:31–33 – FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER AND SHALL BE JOINED TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH. This mystery is great; but I am speaking with reference to Christ and the church. Nevertheless, each individual among you also is to love his own wife even as himself, and the wife must see to it that she respects her husband.
  • Romans 16:25–27 – Now to Him who is able to establish you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery which has been kept secret for long ages past, but now is manifested, and by the Scriptures of the prophets, according to the commandment of the eternal God, has been made known to all the nations, leading to obedience of faith; to the only wise God, through Jesus Christ, be the glory forever. Amen.
  • 1 Corinthians 2:7–8 – … but we speak God’s wisdom in a mystery, the hidden wisdom which God predestined before the ages to our glory; the wisdom which none of the rulers of this age has understood; for if they had understood it they would not have crucified the Lord of glory …
  • Colossians 1:25–27 – Of this church I was made a minister according to the stewardship from God bestowed on me for your benefit, so that I might fully carry out the preaching of the word of God, that is, the mystery which has been hidden from the past ages and generations, but has now been manifested to His saints, to whom God willed to make known what is the riches of the glory of this mystery among the Gentiles, which is Christ in you, the hope of glory.
  • » The mystery is the life of Christ within … I’m in Christ and Christ is in me
    • 2 Peter 1:3–4 – seeing that His divine power has granted to us everything pertaining to life and godliness, through the true knowledge of Him who called us by His own glory and excellence. For by these He has granted to us His precious and magnificent promises, so that by them you may become partakers of the divine nature, having escaped the corruption that is in the world by lust.
    • Romans 11:33–36 – Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and unfathomable His ways! For WHO HAS KNOWN THE MIND OF THE LORD, OR WHO BECAME HIS COUNSELOR? Or WHO HAS FIRST GIVEN TO HIM THAT IT MIGHT BE PAID BACK TO HIM AGAIN? For from Him and through Him and to Him are all things. To Him be the glory forever. Amen.
  • This is all about Jesus. The great mystery that was hidden from ages and generations which has now been revealed by the Spirit of God … the mystery that is hidden on every page of the Old Testament and revealed on every page of the New is that 
    • Jesus Christ is preeminence, 
    • He is the centrality of the Christian life, 
    • He is the North Star, 
    • He is the supreme focus … 
    • For from Him and through Him and to Him are all things.
  • Major Ian Thomas – “The Christian life can be explained only in terms of Jesus Christ, and if your life as a Christian can still be explained in terms of you – your personality, your willpower, your gift, your talent, your money, your courage, your scholarship, your dedication, your sacrifice, or your anything – than although you may have the Christian life, you are not yet living it! … It has got to become obvious to others that the kind of life you are living is … beyond all human explanation!”
  • Galatians 2:20 – I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me.
