25 years ago when I converted to Pentecostalism it was very common to hear people say "he got the
revelation of one God".
Often it was even added to the events of conversion... "he received the revlation of one God while driving his car, and was baptised in Jesus Name the next night. It was a specific and distinct occurance and added to the three
Acts 2:38 steps - sort of like some others added "sanctification" in the past.
The accompanying teaching was that God opens the understanding and the
revelation could not be received through study and intellect alone.
Do you remember this teaching?
Is it still taught some places?
