do religious people really believe?

[Neo-Scholastic]

It comes from me. Why is that inferior?

I said it come to nothing. But in answer to your question, it is inferior because it comes from you, a finite being, and is based on your relationship with things in this world, that are finite. While the believer is also a finite being, the believer has a relationship with the Infinite.

Except you've got no assurance that it will endure. Neither of us do...We only have one life we can be sure of, after all.

The difference between us is I have assurance in my continuance. A disbeliever, such as yourself, has no such assurance.
