No, I don't believe that atheists can't handle the truth. Our truth is based on faith, strong faith that is, and a belief that does not require any physical evidence to justify. But that's just it. How do you prove God to someone who doesn't believe in Him to begin with if you don't have the proof to show it? That's the very challenging part.
In other words, although I am a Christian, belief itself in this cruel world is stretched thin as it is without any proof to back it up, and you also have atheists fighting the idea of it other than just not believing in it. So, how can one expect to prove or at least cause a shift of faith that would make an atheist turn into believing in God? It really is much harder than it seems.
