So sebastious, your definition of "faith" is an internal belief which doesn't require an explanation?
I'd like to attach an article from the Deist website on this matter....
Faith: This word has been so terribly abused by "revealed" religions that it has come to really mean the suspension of an individual’s God-given reason in order to accept, or at least to tolerate, an unreasonable claim made by a "revealed" religion. It is the only way "revealed" religions can get people to accept such insane and unreasonable claims and ideas as original sin, walking on water, healing the sick without medical care, splitting the Red Sea, etc. Deists prefer to use the word "trust" instead of faith due to the twisted meaning the word "faith" has acquired after centuries of abuse from the "revealed" religions.
