all faith requires the minimum effort of focusing the will. It's scalable. It requires little faith for you to believe your chair will hold you until it breaks. Next time you sit in a chair you will find yourself having less belief that it will hold you and hesitate or sit gingerly. Consciously you will still sit and then you write off the previous experience as a fluke, and continue to maintain the minimalist faith in the chair and believe it will hold you. Subconsciously that one time isn't erased and still maintains as a nagging doubt in your head./ That is what faith is for, to help silence those nagging doubts.

My faith in God is very similar to the sun coming up tomorrow, It's proven to me so very little faith is necessary. Sometimes good arguements on here to shake the faith, but they have to surmount all of the belief I have before I rely solely on faith. Then I could easily switch beliefs to something else. Faith in God appears to require tons of faith to you simply because you don't believe in it, so to come to that conclusion you'd have to rationalize away all your proofs against it then "have faith" to switch.

In case I didn't clarify the last question. Faith is chosen because your will is focusing on wanting something consciouly, dredging it from the endless possibilities of the subconscious into "reality". That is a choice.
