Damocles,
For the record, I haven't found you to be offensive.
I wasn't comparing your God experience with mine. My illustration about computing was for the purpose of showing how any person seeking God may eventually find him. I'm sorry I failed to make that clear enough.
Perhaps you can illustrate for me how it is that a person can be "receptive to the holy spirit" and still not know with certainty that the spirit's Giver really exists.
God reveals himself and gives his spirit to those whom he chooses. It isn't for me to determine your sincerity, and I have no explanation of why he reveals himself to me and many others but not to you.
Your daughter is simply repeating the Watchtower's party line. That's all she knows. I was a JW for 50 years and knew very few among them who would or even could talk of a personal relationship with God. JWs look to the Watchtower Society as their mother, and for the most part their spiritual relationship is with the organization, not with God. They fear far more what the organization thinks of them than they contemplate what God thinks.

... it is common for us each to take the same facts and come to very, very different conclusions.
I'm sorry if I haven't made it clear enough, but my relationship with God is an experiential reality, not merely a state of mind.
