Have you ever wondered whether there is an almighty, all-knowing, all-wise, and all-loving God Who wants a personal relationship with each of us badly enough to literally die for it? Well, fortunately there’s a simple test you can do that cannot fail to tell you whether or not such a God exists. Ready? All you have to do is say, “God, can I see You for a minute? I want to talk with you.” Then have a digital camera ready. If He shows up to talk to you, take His picture and post it on the web, and you will have proven that He exists. The cool thing is that this test will work for anybody and everybody, so if anyone claims you might have faked the photo, they can just repeat the test themselves.
What makes this test infallible is the nature of God, as specified in the test. Because He is all-powerful, all-knowing, and all-wise, by definition there is no greater power than God to prevent Him from showing up if He wants to. And because He is all-loving and wants a personal relationship with each of us, He wants (by definition) to show up to participate in that relationship as long as no greater power is able to prevent him. It is thus impossible, by definition, for this test to fail to reveal the truth about whether such a God exists.
In fact, there’s only one flaw.
