That only works if you understand what is meant by, FAITH, in the context of Christ. I think you are confusing FAITH with BELIEF.
Belief, you do nothing, it is intellectual. Faith is the living embodiment of being Christian. It includes belief, but more, Faith is belief that comes to life in service to humanity for the love of Christ. Faith can not exist in the absence of deeds, when it does we call it belief.
I think you are mistaking Faith for a dictionary version of its meaning which is more to do with belief.
