Truly a Believer
"If you don't believe anymore... you can still just "act" as if you do. You can act as if you believe. I know this might seem lame or false, but it's just a matter of commitment. If you totally throw yourself into the role of "a believer" you will be convincing. You may even be able to convince yourself. If you are a "method actor" you might remember a time where you did believe, or a very particular incident where belief enveloped your being. You can use it. You can act, drawing upon that particular time and impulse. If you are an accomplished actor it will be really hard to tell if you are truly a believer or just acting.
