The Mystery Hidden for Ages
One of the most distinctive features of the New Testament concept of mystery is its temporal structure. The mystery was not always known. It was hidden — deliberately, purposefully, by God Himself — for ages and generations before it was disclosed. This hiddenness is not an accident or an oversight. It is part of the plan.
The Key Passages
"...the mystery hidden for ages and generations but now revealed to his saints."— Colossians 1:26 (ESV)
"...to bring to light for everyone what is the plan of the mystery hidden for ages in God, who created all things."— Ephesians 3:9 (ESV)
"...according to the revelation of the mystery that was kept secret for long ages but has now been disclosed."— Romans 16:25-26 (ESV)
"...we impart a secret and hidden wisdom of God, which God decreed before the ages for our glory."— 1 Corinthians 2:7 (ESV)
Taken together, these passages reveal a consistent timeline:
- Before the ages — God planned the mystery. It existed in His counsel before creation (1 Corinthians 2:7, Ephesians 1:4).
- For ages and generations — God kept it hidden. Throughout the Old Testament era, the mystery was not fully disclosed, though hints were given through the prophets and through figures like Daniel (see Mystery in the Old Testament).
- Now — God has revealed it. Through Christ's death and resurrection, through the Spirit, and through the apostolic preaching, the mystery has been made known.
Why Was It Hidden?
Paul does not give a single definitive answer to why God chose to hide the mystery for so long. But several factors emerge from the texts:
- The "fullness of time" (Ephesians 1:10, Galatians 4:4) — God had a specific moment in history when He intended to act. The mystery was hidden until that moment arrived.
- So that human wisdom could not claim credit — In 1 Corinthians 2:6-8, Paul notes that the "rulers of this age" did not understand God's wisdom. The hiddenness ensured that the gospel could not be co-opted by worldly power or presented as a human achievement.
- To magnify the revelation — The long period of hiddenness makes the disclosure more dramatic and more clearly an act of divine grace. The phrase "but now" (nuni de) in passages like Colossians 1:26 and Romans 16:26 carries a sense of dramatic unveiling.
"But Now Revealed"
The word "now" is crucial. The hiddenness is past tense. This is not an ongoing state of ignorance but a completed transition from concealment to disclosure. The appropriate response to a revealed mystery is not mystification but understanding, gratitude, and proclamation. As Paul says in Colossians 1:28: "Him we proclaim, warning everyone and teaching everyone with all wisdom." The mystery is now available to be understood by all who hear.
Connection to Other Mystery Passages
The "hidden for ages, now revealed" structure is the backbone of Paul's entire mystery theology. It connects to:
- The Mystery of Christ — the specific content of what was hidden (Gentile inclusion).
- The Mystery of the Gospel — the revealed message that must now be proclaimed.
- The Mystery of God's Will — the grand plan of which the hiddenness was a part.
- Stewards of the Mysteries — those entrusted with the revealed truth.
- The Mystery of God Finished — the future completion of everything that has been revealed.
