4c During the church age, the age of mystery, Christ is building up the church, the Body of Christ, to be His bride — Matt. 16:18; Rom. 12:4-5; 1 Cor. 12:12, 27; Eph. 4:16; Col. 1:18; Rev. 19:7-9.
54 The kingdom of the heavens, the gospel, the indwelling of Christ, and the coming resurrection and transfiguration of the saints are all mysteries that were hidden in the times of the ages — Matt. 13:11; Eph. 6:19; Col. 1:26-27; 1 Cor. 15:51-53.
