In Mark 4:11 the Lord Jesus spoke of “the mystery of the kingdom of God.” This mystery includes New Jerusalem, the ultimate stage of God’s kingdom.
Paul often speaks of this mystery, as in Romans 16:25, “…my gospel, that is, the proclamation of Jesus Christ, according to the revelation of the mystery, which has been kept in silence in the times of the ages.” And Colossians 1:26, “The mystery which has been hidden from the ages and from the generations…”
This mystery, even the existence of this mystery, was hidden in God before the Lord Jesus began to minister. The Lord said something about it in His parables. Paul spoke further, for example “I came to you, brothers,…announcing to you the mystery of God” (1 Cor. 2:1).
Paul and his companions were “servants of Christ and stewards of the mysteries of God” (1 Cor. 4:1). And he asked for prayer “that utterance may be given to me in the opening of my mouth, to make known in boldness the mystery of the gospel” (Eph. 6:19).
He was announcing the mystery because God predestinated the wisdom hidden in it “before the ages for our glory” (1 Cor. 2:7). Since the wisdom of the mystery is for our glory, it is for our glorification and participation in New Jerusalem.
Today we are in the age of mystery and New Jerusalem surely is part of this mystery. But, “in the days of the voice of the seventh angel when he is about to trumpet, then the mystery of God is finished” (Rev. 10:7).
“The seventh angel trumpeted; and there were loud voices in heaven, saying, The kingdom of the world has become the kingdom of our Lord and of His Christ, and He will reign forever and ever” (Rev. 11:15). This is from the second coming of Christ unto eternity, including New Jerusalem.
