The kind of faith which is a trust without reservation that brings joy to the believer is a wonderful thing.
It need not be a matter of proof or evidence arguements any more than observable facts need to be worshipped.

There is one supreme evidence of faith that goes beyond any catagory of religion or secular definition and that is...
caring.

Caring is the single most important and redemtive quality in a human being.

For an artist or lay person alike, caring is obvious in their work as it is with its absence.

No matter how a person comes to express their caring is a beautiful thing. There may be people who need conscience to be taught. If that is in a religious format they will be better for it. If it is in a secular format they will be better off for learning. I would hope that it is a rarity for a person to have no inate conscience but evidence in the world may hold a contrary viewpoint. Perhaps mortality itself is to blame when a rich person still can never have enough wealth to stave off death.
