How do the different basic doctrines Paul teaches relate to the revelation of the mystery?
The various basic doctrines Paul teaches are distinct concepts, yet all are part of the revelation of the mystery. Paul's gospel is preached according to that revelation, which had been kept secret since the ages began but was revealed when God called Paul as the Apostle of the Gentiles.
Les teaches that these secrets were held by God throughout human history and revealed only when He called the Apostle Paul to be the Apostle of the Gentiles (s218-s224). In Romans 16:25, Paul writes that God is able to establish believers according to his gospel and the preaching of Jesus Christ according to the revelation of the mystery (s241-s246). Les explains that the gospel Paul preached is part and parcel of these revelations of secret things never revealed before (s248-s254). These basic doctrines are different concepts, but all are part of that revelation of the mystery (s236-s240). The verse says this mystery was kept secret since the world or ages began (s255-s257), and Deuteronomy 29:29 confirms God can keep things secret as long as He wants (s258-s260). Once He reveals it, it becomes human responsibility to believe it (s261-s262).
Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery, which was kept secret since the world began,
