Hope is not a christian concept and is definitely not supernatural. It's origins point toward this:

"Putting the Indo-European root and the Hebrew and Greek equivalent together, yields a meaning of the word “hope” as a confident expectation that a desirable change is likely to happen." http://hope-international.blogspot.com/2011/04/meaning-of-hope.html

There will not necessarily be a manifested physical "production" of it, either, and it is more than just wishful thinking.

It is a concept, it is intangible.

I'm not real sure that I understand what you mean here, but I really hope (unfounded, possibly in this case, by this definition, haha) that ppl aren't living lives "that [are] subject to their hope", especially if they are using your definition. To hope, by your definition, is a passive thing- there is no action taking place, any desirable change is luck or accidental good fortune.

If accompanied by steps toward change, then it moves into the realm of the true definition, which is a confident expectation that a desirable outcome is possible.

A person can come to that conclusion based on evidence (past experiences and knowledge learned using results of scientific study) or they can come to that conclusion based on blind faith in their skydaddy.

At that point, I put more trust in my hope (for certain outcomes) then in a blind hope borne of a mythical story.

Sorry, but hope is not only in the purvew of the god-believers...
