Why Is Atheism So Important?

What good will atheism do when it's only a temporary condition?
It offers no hope for those who claim to be its follower; as a matter of fact, it takes away hope from those who need to have hope. It's a wonder why we have so many suicides.
It'll never win against the Truth of God being that it's a lie from the very beginning knowing that no lie can win out against the Truth of God.
Those who claim to follow it refuse to support it giving the lame excuse that they don't have to support it. Why? Do they know deep in their hearts that it really is a lie? If that is so, why do they keep following it? Do they really hate God that much?
Atheism is for the dead and not the living. As Jesus said in Luke 20:38, "For He is not the God of the dead but of the living, for all live to Him.”
Understand, I'm seeking answers and not arguments.
