Since faith is a ??belief that is not based on proof?.

According to the scriptures, faith is the substance of things hoped for, the evidence of things not seen. So it's impossible to have faith without proof. I'm not sure where your definition comes from but faith is a scriptural word and any definition of this word is probably an interpretation of the meaning in the bible. Another words, faith is a person. So if you have faith, you have substance and proof. Obviously my views are always from the bible.
