We are to have, as is said and believed when it comes to life and religion, "faith," but when it comes to exercising faith on any thing, a very crucial aspect of having and exercising "faith" isn't normally mentioned. Justification is a book discussing what isn't when it comes to "faith," talked about. In order to have faith in anything, we need to possess a living and working knowledge of what we would have faith in. Justification looks into how the bible defines the process of acquiring and maintaining "faith," introducing the reader to a pattern of thought revolving around the idea that, even if it is true that the conversation is unhealthy without faith, the sufficiency of the conversation is based upon the knowledge it has not only on the Bible's philosophy, but also on its experience in that philosophy, making personal knowledge an integral part of having and exercising "faith."
