Who did God reveal the mystery to?
God revealed the mystery, kept secret since the world began, to the Apostle Paul. Paul's doctrines comprise the whole circle of this mystery. This revelation was not made known until God chose to reveal it to him. The deeper revelations came out later in Paul's prison epistles, especially Ephesians.
Les teaches that the mystery was kept secret in the mind of God since the world began. It was not revealed until God made it known to Paul, the man to whom the revelation was given. Les explains that this mystery is the whole circle of Paul's doctrines. He suggests that much of it came out during Paul's three years at Sinai, and that the deeper revelations appear in Ephesians. Les also notes that Paul may have received these deeper doctrines while imprisoned in Caesarea, waiting to go to Rome.
