Galatians 1:16

ἀποκαλύψαι … ἐν ἐμοὶ. These words taken alone might denote either an inward revelation to Paul himself, or a revelation through him to the Gentiles. But the context is decisive in favour of the former: for this revelation is not only associated closely with his conversion and his personal history between that and the visit to Arabia, but it is expressly stated that it was granted with a view to future preaching (ἵνα …).

The context distinguishes this revelation from the call; it cannot therefore be identified with the previous vision of Christ on the way, but (as the words ἐν ἐμοί import) was an inward and spiritual revelation which followed that appeal to eye and ear. The history corroborates this view: for it relates that Saul, after his vision, spent three days in solitary communion with himself and God before he was admitted to Christian baptism. προσανεθέμην. This compound verb denotes (as in Galatians 2:6) additional communication. After direct revelation from God Saul had no occasion to seek further advice from man. There is an apparent reminiscence in thought and language of Christ's words, flesh and blood hath not revealed it unto thee, but My Father.
