Yes, it does perplex me at times, but then I realize everyone needs to define their own belief system.
For me, I just see religion entirely as group-think and man trying to interpet God. When you add in how many times and years the bible was rewritten and even constructed, it is a wonder that anyone leaving the JW religion would want to be apart of a religion in any way.
But as I am one not to walk someone else's path, these are just my thoughts and if it works for someone else, I wish them well.
