OK. So you don't want to serve God or even believe in Him given your current spiritual state. I don't blame you. I wouldn't either if I was in your shoes. In fact, I have never met a person who naturally wants to serve God. Man's "wiring" is too messed up for that sort of thing.
But what if your heart was changed? What if God gave you a new heart and a new mind? What if God placed His holy Presence within you, and you began to experience things you have never experienced?
Now hold that thought.
It is impossible for you to know for sure that God won't do that for you. Simply impossible. Even if your heart is rock hard toward God, there is no way you can know for sure what a new heart would do for you.
