From your own experiences you should know that relationships grow. Conceptual belief is just the starting point.Remember, we were talking about people who fail to experience God. They simply fail to "feel" God's presence as you or other believers might. That's the point. So many religious folks look at atheists and say "Just believe in God! It's simple!" But it really isn't that simple. One must feel God to have some sort of "relationship" with him. Otherwise you are simply "worshiping" something that doesn't even feel real to you.
