The mystery of God, namely, Jesus Christ, is not a mystery anymore (Colossians 2:2-3).

Behind all those ceremonies, temple regulations, holiday celebrations, and animal sacrifices were a mystery for the people of God, especially for priests and prophets.

But now, for us, after the death and resurrection of Jesus Christ, the mystery of God had been revealed.

So, whenever we read “mystery” in the New Testament, it is pointing us to the truth of God that has been hidden for a long time but has been revealed after the cross of Christ.

In one of their recent blogs, Walk Thru the Bible Ministry explains this concept this way:

“In the Bible, a mystery is nothing mysterious but something previously unknown. The mystery was that Jews and Gentiles would join together to form a new entity–the church. This mystery was foretold by Jesus, but the details of the doctrine, walk, and destiny of the church were communicated by Paul and his fellow apostles.”

Some people read Ephesians 5:32 and conclude that marriage is a mystery; they believe and think that there is something mysterious about marriage between one man and one woman that is yet to be revealed.

Paul writes, “This is a profound mystery—but I am talking about Christ and the church.” (Ephesians 5:32)

Paul here is not saying that there is a mystery about marriage that is yet to be revealed; rather, he is saying that the mystery that was hidden for a long time has now been revealed. The truth of a marriage between one man and one woman was “something previously unknown” – the fact that a husband is a reflection of Jesus and a wife is a reflection of the Church, was something hidden. But now this hidden thing, the mystery, is no more a mystery, but the revealed truth of God. Praise God! ///
