I think you don't have a clear definition of what faith is . Faith does not mean you keep a belief if it does not grow . Blind faith is not good . Faith in things that are true will produce fruits. A non-religious example of what faith is. I believed I could repair my head gasket on my car. I had seen it done ,I have the tools ,I have the manual I exercized my faith by acting on this belief. I could not .I was able to take it apart but was never able to put it back together . I put my faith in things that were not true. A while back my computor crashed. I believed that I was inteligent enough to read and learn how to fix it . I acted on that belief. The moment you act, it ceases to be a belief and becomes an act of faith. I read and learned and over time I learned and repaired it . In James 2:20-24 It teaches about faith and action. Applied in religion we act on what we learn in church or in the scriptures , if it produces fruit then it was true and our faith grows and so does our belief. Alvarado
