Existence of a Supreme Being?

God works in mysterious ways. This is the problem that some people have with religion. They want validation that He exists. If they don't see any evidence, they don't believe HE exists. Well, this is what we call faith. Some of these people were raised in religious families. They lose their faith when something tragic happens to them or a loved them. They say to themselves " If there is a God, why does he let bad things happen to good people?" "Why are there wars?" "Why are people starving around the world?" So they turn their back on religion. They argue that people who go to church are hypocrites. They say people use it a crutch. There is validity in that argument but I think the majority of these people are descent human beings with good hearts. There others who find themselves again. Who is to judge? The irony here is that these non-believers will be the first ones to say "Please God help me" when an actual tragically befalls them. When one is close to death they seem to harness a belief system all of a sudden. now they are scared, they will cling on the hope that there is more, that there might be more in the beyond. Any thoughts?
