It's important to understand that if someone calls themselves a Christian, it does not automatically make everything they do an act of Christianity, even if they say it is.

The role of the Christian is to let other people know what Jesus has done, not to think of themselves as a member of an exclusive Heaven club.

Naturalistic atheism debunks itself. It has no power to explain even some of the most basic principles of the universe and existence. It cannot even explain how its own claims can be reasonably believed.

The atheist might have no proof for the supernatural, but they also have no proof against it. If we start at a neutral position of not knowing, we can't move away from it until we have proof or evidence either way.

Whether you say that a god does exist, or that none do, it is a claim to know (or at least believe in) something. Once you claim to know something, you can't call that a lack of belief in the opposite view and then say it's the place that you started.

The claim to know that no god exists is just irrational. The non-existence of any god has no evidence, let alone proof. To know something for certain there must be proof. To hold to a belief there must be evidence. Until then, the only actual reasonable position is agnosticism.
