Ephesians 3:5
Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;
The mystery is something that has not been made known; it was kept secret since before the foundation of the world. But it was now revealed to the Apostle Paul by the Lord Jesus Christ, and many have asked if only the members of the body of Christ knew about the mystery. I don’t believe so, because verse 5 says that it was not made known to the sons of men in times past. But now it is revealed to the apostles and prophets, but how is this? It is by the Spirit, but did he reveal it to them individually or did they learn it through the teaching of Paul and the Spirit using the word to teach them. We have seen in Second Corinthians Two that the Holy Spirit is our teacher, so it is not surprising that others learned about the mystery, but it was not until after it had been revealed to the Apostle Paul.
Rejoicing in Grace,
