Great post Dave. I was in the Assembly at that time (1978) and know I went to the Seminar you mentioned (Wars of David). Unfortunately I didn't save the notes from a lot of those Seminars, and don't recall a lot about it. But I had a similar experience in leaving my mother's house too (although my experience with that happened in 19-74-1975 time frame in the Assembly).
Well said concerning your son. I wish him the very best! I'm glad you are letting him become his own person and leaving him in God's hands.
