Did Paul receive revelation from the Lord only on the road to Damascus?
No. Paul did not receive revelation from the Lord only on the road to Damascus; the Lord also revealed things to him in other areas. His revelations went beyond what Peter and the Eleven could comprehend, and Paul operated by revelation.
Les explains that Paul’s revelation from the Lord was not limited to the road to Damascus. The Lord revealed these things to Paul in other areas as well, and did so in such a way that even Peter and the Eleven could not comprehend what Paul was talking about when you go on into Galatians chapter 2. It was way beyond anything they had ever heard. Paul, therefore, operates by revelation.
