As I read the cited verses, the "mystery" to which Paul is referring pertains to something that was previously hidden, but has now been revealed. It is a twofold revelation, referring not only to the ability of Christ (now that He has been incarnated and also completed His atoning work and returned to the Father) to both sanctify and dwell within believers; but also to the expansion of the body of those believers to include not only Jews, but also Gentiles (such as those to whom Paul was writing),

Based on 2 theological dictionaries, Eastons's Bible Dictionary and International Standard Bible Encyclopedia, the "mystery" in Colossians 1:27 and Col 2:2-3 is not a riddle or something impossible to understand. It is a gospel truth, once hidden in God's plan, but now publicly announced: The mystery is revealed (Col. 1:27) which is this: Christ Himself living in you, the Gentile believer, which is your absolute guarantee of future glory with God. The content of the mystery (Col. 2:2-3) is this; Christ Himself is the ultimate treasure chest containing all the wisdom and knowledge you will ever need. You do not look anywhere else. So, the "mystery" is not a what but a who: Jesus Christ, revealed as your indwelling Savior and your complete source of wisdom.

What is this "mystery"? (Colossians 1:27; 2:2-3) The Meaning of the Mystery Christ in You: In Colossians 1:27, the apostle Paul explains that the mystery is "Christ in you, the hope of glory". This means Jesus permanently indwells every believer, assuring them of future eternal life. Paul explains that this truth was concealed from past generations and ages, but is now revealed to God's people. Since "the bearing witness to Jesus is what inspires prophesying," "the sacred secret of God" must centre around Christ. (Re 19:10; Col 2:2) All "the sacred secrets" of God concern his Messianic Kingdom. (Mt 13:11) The apostle Paul writes to fellow Christians: Col 2:2, 3, 9. "that their hearts may be comforted, they being knit together in love, and unto all riches of the full assurance of understanding, that they may know the mystery of God, even Christ, 3 in whom are all the treasures of wisdom and knowledge hidden." 9. "for in him dwelleth all the fulness of the Godhead bodily," The "mystery" in Colossians 1:27 and Colossians 2:2–3 is Paul's term for a truth God planned from the beginning but revealed fully only through Christ. It is not a puzzle or secret code; it is a divine reality once hidden and now openly proclaimed. Paul states the mystery plainly: "Christ in you, the hope of glory" (Colossians 1:27). This means God's presence is no longer confined to a temple or a nation. Through Christ, God dwells within all who believe—Jew or Gentile. The mystery reveals that salvation, fellowship with God, and future glory are given through union with Christ. This overturns old boundaries. What was once limited to Israel is now extended to the nations. The mystery is the formation of a new people whose identity is rooted in Christ Himself. The mystery is God's plan now revealed in Christ. Paul says believers gain "full assurance of understanding" in Christ, in whom "are hidden all the treasures of wisdom and knowledge" (Colossians 2:2–3). This means: Christ is the centre of God's revelation. Everything God intends humanity to know about salvation, wisdom, and truth is found in Him. What was once concealed in shadows—prophecies, promises, symbols—is now unveiled through His life, death, and resurrection. The mystery is not vague spirituality; it is the unveiling of God's eternal purpose through the person of Jesus. The mystery forms a new unified people. Elsewhere Paul expands this idea: “This mystery is that the Gentiles are fellow heirs… and partakers of the promise in Christ Jesus" (Ephesians 3:6). The mystery includes the creation of one body from all nations, united not by ethnicity or law but by Christ's Spirit. The mystery transforms the believer's life. Because Christ dwells within His people: They share His life (Galatians 2:20). They reflect His character (Romans 8:29). They anticipate His glory (Romans 8:17). The mystery is not merely doctrinal; it is experiential. It shapes identity, hope, and daily conduct. Summary The mystery in Colossians is the revelation of God's long‑hidden plan: Christ living in His people, forming a new humanity, and revealing God's wisdom and salvation to the world. It is the unveiling of God's purpose through Christ, once concealed, now fully revealed, and eternally transformative.
