Mr. Bojangles says he doesn't believe in God.  His justification is that there is no proof.  However, faith by definition does not rely on logical proof or material evidence.  Faith is a very powerful word and has a broad usage.  Every single person who believes in any kind of god or deity must have faith because it is impossible to prove the existence of such beings.  A few synonyms of faith are:  confidence, trust, reliance, assurance, conviction, devotion, and loyalty.  Faith is the confident certainty in the truth, value, or trustworthiness of a person, idea, or anything else which is not based on concrete proof or evidence.
