A God who let us prove his existence would be an idol.
The best proof of love is trust.
America: a country where everything is done to prove life isn't tragic.
Faced with the choice between changing one's mind and proving that there is no need to do so, almost everyone gets busy on the proof.
—John Kenneth Galbraith
I show you doubt, to prove that faith exists.
I don't believe it. Prove it to me and I still won't believe it.
