Be Or Do?

Why do Christians do what they do? Everyone wakes up in the morning with a set of beliefs about the kind of person they believe they are. And then they spend their day doing things that may (or may not) line up with those beliefs.  We are all human beings and human doings. So what is the more accurate reflection of who we really are; who we think we be, or what we really do?   If we be Christians… what does the bible say we should be doing? Because being without doing is just pretending.
