Mystery, the Greek musthrion, is something unknown until revealed to the initiate. In the Bible it refers to God’s secrets, His counsels and purposes, which are not known to man apart from His special revelation in Scripture or by His prophets. It is particularly used in the New Testament of truth unknown in the Old Testament, but revealed in New Testament times. Eleven different mystery truths can be distinguished in the New Testament (Matt. 13:11; Rom. 11:1-25; 1 Cor. 15:51-57; Eph. 3:1-11; 5:25-32; Col. 1:26-27; 2:2; 1 Thess. 2:7; 1 Tim. 3:16; Rev. 1:20; 10:7; 17:5,7).
