What Is Faith?

Faith is a means of controlling the central nervous system, specifically the production of neurochemicals which cause a person to have feelings such as joy, bliss, idefatigableness, a sense of peace, a sense of destiny, etc.

This is why people are willing to give themselves over to what appear to be charlatans and thieves, because those charlatans and those thieves provide the service of helping their "believers" maintain a steady flow of the neurochemicals to which they often become addicted.
