Paul says that the "gospel" (good news) he preached was 'not man's gospel' but a "revelation of Jesus Christ". He uses an important and specific word... it was an 'apokalypsis'. Dunn says this is a word that denotes a disclosure given from heaven, with heavenly authority, usually of heavenly secrets" (James Dunn, The Epistle to the Galatians, 53). What exactly was that message?
