Virusdoc posted his latest (Part IV) in his seies of posts on testing the exsistance of the Christian God. Frankly, as I said today in the comments, I didn't think that this would be a fruitful search. He's looking, as a scientist, for a hypothesis and an experiment to prove that God exists. People have been wanting this kind of proof forever, why sould he be smarter than the millions before him that tried?
But today he hit on something that was golden:
... these passages make the prediction that each and every individual can obtain real, personal, and tangible evidence of the existence of God by doing something ridiculously simple, yet apparently quite valuable to God: seek Him. Ask Him to reveal Himself. Suspend your disbelief long enough to open your mind to the possibility of His existence. If the God of the Bible exists, then He will respond to this tiny act of faith by revealing himself.So there it is, a simple test for the existence of God. Why didn't I think of that? Go check it out. And don't forget Part I, Part II and Part III.
