I've only read page one. I will catch up when I can. But I must say that Finkelstein nailed it.
Every god worshiped or imagined by man originated solely in the human imagination so if you want to imagine a god and have relationship with
one, then use your own imagination. It has worked for billions of people for thousands of years.
Non=Christians have heard/felt God (or His Spirit or some other term for the supernatural) Mormons, JW's, all kinds of different believers are sure they have heard or felt the calling, presence, voice, etc. Some can say that is possible, but many of them have heard/felt things that contradict others who have heard/felt God's presence.
Not all of them are faking it (as some Governing Body members must be doing). With Christianity, it seems that most everyone will tell you that you have to believe that it will happen before it will happen. They might phrase it as "You must first kiss the son" or "You must first accept that Jesus died for your sins" or "You must have full faith first" or whatever. But that just leads to people believing that they should hear/feel God's presence, therefore they must have. It can lead to a slippery slope of allowing one's own mind/imagination to fill in for God/Holy Spirit/Christ/Jah. It might have started with a coincidental event that seemed to be an answer to prayers or it might have started with indigestion or a brain tumor.
If you start with full faith that Jehovah's Witnesses offer "the truth," you know how you can arrive at that same conclusion with no ability to see past that idea. That is a dangerous place to start, and starting at faith that God can and will contact you will lead to similar problems.
Oh, it's so touchy to say it straight like that. So many will automatically object to what I said and tell me I don't know. Okay, go find out for yourself. Start by learning about cognitive dissonance and religious ferver, add in stuff like "the Great Disappointment" of the Millerites. Read about Joseph Smith and the founding of the book of Mormon.
