I have a relationship with my parents that would blow you away. They passed on many years ago. I have a relationship with my mentors in much the same way. They do not discuss the afterlife to me, they discuss my problems. They are all comfortable. Can I prove it? No. Can I know it? Yes! Your reasoning for going after proof of God will always be hidden. He has enough scripture to explain. Take it or Leave it but just saying there is no proof for your existence doesn’t deny his salvation to the masses. Maybe the life works of C.S. Lewis is your guide.
Even members of the same faith disparage each others' beliefs with venomous hatred that spills out all over forums like this one, anti-Catholic, anti-Protestant, anti-Orthodox, etc.
If this is all neatly explained in the Bible and the Holy Spirit leads all these believers, it surely doesn't look very convincing.
If you believe in something that is your prerogative. I hope this goes with the understanding that faith is not a proof. Neither are anecdotal accounts. I don't ask anyone to prove their faith. It is only when faith is presented as a matter of fact that I ask for proof.
When confronted over this issue I get answers like "God is not a fact." Then what is he? I think people who can't prove their statements of fact should not make them, but they should not be surprised or offended when they are asked to prove them. That's all.
