3 According to[a] revelation the mystery was made known to me, just as I wrote beforehand in brief, 4 so that you may be able when you read[b] to understand my insight into the mystery of Christ 5 (which in other generations was not made known to the sons of men as it has now been revealed to his holy apostles and prophets by the Spirit): 6 that the Gentiles are fellow heirs, and fellow members of the body, and fellow sharers of the promise in Christ Jesus through the gospel, 7 of which I became a servant, according to the gift of God’s grace given to me, according to the working of his power.
Mysteries. Everyone loves a good mystery – even God!
The verses above show that there is a mystery that was revealed to Paul. But notice, it was not fully disclosed. Paul said “so that you may be able to understand my insight”.
In the great wisdom and knowledge of Paul, with Jesus personally teaching him in Arabia (Galatians 1:17) and memorizing the Torah, it would seem that he knew a lot – if not everything! But even so, he still did not fully comprehend the mystery of Jesus Christ. The original word for insight here is “sunesis”, which “means putting together in the mind, hence: understanding, practical discernment, intellect”. Paul had to put lay out what he knew to connect the dots, so that he could try to discern this mystery. Notice he said “my insight”. This was the loftiness of God’s thoughts that even the greatest apostle could only provide insights to the mystery.
It is also the Spirit that reveals things.
