Or more precisely, your athiesm is just an unsupported faith in a solely material existence without a God.
Christians worship what they know since they have been touched by the Holy Spirit; so they have actual experienced evidence for their beliefs. The athiest is generally making an argument from silence; but the silence is solely his own. If he is arguing to a Christian there is no silence, no lack of concrete evidence at all on the Christian’s part, he knows that God exists because God has touched him.
Ironically, in each case the individual's testimony is consistent with his experience; for one the existence of God is proven fact, but for the other there is no experiential evidence, and the best perspective such a one can muster on such a basis is agnosticism.
As a Christian I have no beef with the agnostic on that basis, though we may disagree on other points. However, I do have rather a bone to pick with the atheist who generalizes from his own absence of evidence a universal evidence of God's absence.
A reasonable argument. But ...
You can apply the same argument to an Islamic Suicide Bomber. He would claim that he, as well, was touched by his version of the Holy Spirit. And we believe that he is wrong don't we? Is there any doubt that his feelings about what he believes to be the truth are every bit as strong as the most devout Christian?
The bottom line for me is that any religion is based on faith and not proof of any kind. That's OK. What is not OK is to confuse strong belief and gut feel or whatever you want to call it with proof in any sense. It is not proof. It is simply a deep seated faith that you know what is right.
Country music doesn't have to be politically correct. We sing about God because we believe in Him. We are not trying to offend anybody, but the evidence that we have seen of Him in our small little lives trumps your opinion about whether or not He exists.
Oh, let's not get into this topic.
I see no evidence supporting your faith, you see none supporting my lack of such. Let's leave it there.
