Godschild, what I'm saying is you need to be careful of your wording. You state you are 100% certain of knowing something that is not empirically verifiable. I think it safer to say you are 100% CONFIDENT in his existence, but that is different than KNOWING. I too am confident that the God of the Bible is real and have seen the evidence in history, morality, the universe and in my life and in others in order to be persuaded enough to have faith in Him. But I cannot make that statement that I KNOW, because to know something requires "special knowledge". Knowledge comes from the greek "gnosis" meaning experiential knowledge or applied knowledge in personal experiences. In modern times, "knowledge" needs to be testable, empirically verifiable. Personal knowledge is not verifiable, so when you say you "know" something with 100% certainty, people will want proof. But you cannot prove to others using personal experiences as evidence.
We are not made happy by what we acquire but by what we appreciate.
