Perry,
I agree with you and have experienced similar feelings/chills when I pray or focus on my beliefs of God.
The question I have is how does this prove that God exists or is real? Just because I "feel" something or I get chills when I pray or "the spirit" comes over me and I cry during giving a testimonial of my belief doesn't prove that God exists. It may prove that I believe but it doesn't seem like concrete evidence.
What proves that God exists?
