Religion is defined as a belief system. Everyone has faith in something. But the question is: which worldview can make sense out logic, reason and knowledge?
“Are we not to call Christ ours because we have not made him but only received him? Again, if we are the makers of things that are called ours, then we must have made our eyes, we must have made our hands, we must have made our feet, unless eyes, hands and feet are not to be called ours.”
Martin Luther, The Bondage of the Will
Imagine a person who comes in here tonight and argues 'no air exists' but continues to breathe air while he argues. Now intellectually, atheists continue to breathe - they continue to use reason and draw scientific conclusions [which assumes an orderly universe], to make moral judgments [which assumes absolute values] - but the atheistic view of things would in theory make such 'breathing' impossible. They are breathing God's air all the time they are arguing against him.
