Really? If you examine history, you can't find examples of dreadful sinners living full and rich lives, and dedicated believers dying in abject misery? I certainly can.And which religion doesn't say that? They can say it sounds true. It feels true. They can feel it in their heart. That it makes sense that there must be a God.
But I think a big part of belief is kind of like a self-fulling prophecy. They are told if they do good God will reward them. If they do bad God will punish them. But, sometimes, what seems like something bad, it's only God testing them to help that grow. And sure enough, that is exactly what happens. God rewards them, punishes them and tests them. That's gotta be proof he's real. Right?
Doesn't seem like much proof to me.
