I sort of thought I did, but I often wondered about that even during my JW prime. To me, it's difficult to know for sure. It was kind of hard to love somebody I had never seen or heard. Didn't know what to picture in my mind, though I always pictured something like that picture of him in the Revelation Climax book - the one of him sitting on the throne surrounded by the 24 elders.
I often prayed at night all alone outside under a starry sky and I felt appreciation and a sort of closeness, but having never received any answers (that I'm aware of) or ever getting any indication that my prayers were even heard, I found it dfficult to continue to feel close and appreciative.
