What is the preaching of Jesus Christ according to the revelation of the mystery (Romans 16:25)?
In this context we learn that the mystery that is in view is one that had been hushed since the ages began. So it is not the administration of the mystery which was hid from ages and generations and had its plans made before the ages began. This mystery, that had been hushed had been made known by the prophets as the context tells us, so it is not the mystery of Ephesians and Colossians. Also this mystery in Romans is made known to all nations for the obedience of faith. In the structure outline of Romans this is explained by the same words appearing in 1:1-5. It is the preaching of Jesus Christ as the Son of God, but connected with His being the seed of David. So then this is kingdom preaching and declares Jesus Christ not only the anointed one or Messiah, but truly the Son of God.
