“To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory.” (Colossians 1:27)
The New Covenant includes a mystery Paul had the privilege of revealing to the Gentiles (Colossians 1:24-29). The history and prophecies of the Old Covenant contained a few hints of God’s plan for the last days, but the focus was centered on the “fulness of time” when the Messiah would come (Galatians 4:4).
Paul seemed thrilled to “preach among the Gentiles the unsearchable riches of Christ” (Ephesians 3:8) and to have the responsibility of unveiling “the grace of God which is given me to you-ward” (Ephesians 3:2). More than the obligation, Paul felt a dread judgment if he failed (1 Corinthians 9:16). It follows that we should be clear in our own declaration of this mystery.
Simply put, the mystery is “Christ in you, the hope of glory.” Obviously, that is the result of salvation. The new message is the completed work and resurrection of the Lord Jesus. The promises of the prophets and the long history of Israel tend to obscure the eternal plan of God (Ephesians 3:11)—thus the detailed effort of the New Testament writers to amplify the “whosoever will” aspect of the gospel message.
“Of which salvation the prophets have enquired and searched diligently, who prophesied of the grace that should come unto you: Searching what, or what manner of time the Spirit of Christ which was in them did signify, when it testified beforehand the sufferings of Christ, and the glory that should follow. Unto whom it was revealed, that not unto themselves, but unto us they did minister the things, which are now reported unto you by them that have preached the gospel unto you with the Holy Ghost sent down from heaven” (1 Peter 1:10-12).
Now it is possible for the whole world to have a personal and eternal relationship with Jesus Christ. HMM III
