“the mystery hidden for ages and generations but now revealed to his saints. To them God chose to make known how great among the Gentiles are the riches of the glory of this mystery, which is Christ in you, the hope of glory”
The mystery of God that was hidden for ages, God’s means of sharing His glory and riches with those He made in His image and likeness, overcoming the separation of sin and death, is “Christ in you.” The prophets of the Old Testament had seen shadows of what was to come in Christ. Jesus told His disciples with regard to the Helper, the Spirit of truth: “You know him, for he dwells with you and will be in you” (John 14:17). In Christ, our spirits are made alive, directly connected to God through the indwelling Holy Spirit; “we have the mind of Christ” (1 Corinthians 2:16); and “we are members of His body, His flesh, and of His bones” (Ephesians 5:30).
