real?

My lthoughts week have wondered to a new topic, one i have never really thought about a whole lot just accepted the words, and that is being real as chrisitian or in geanral. I think its a hard one to preach about or even talk about in away, I think it turns into can i turn myself into a real christian or how can i make myself real. Does it really happen that way? And for me it has always been a simple answer of walking with God. But when a pastor says it, or as for myself i read an article on the internet and the journalist talked about this culture and being real. So i think the main question is what is really being real? and how do u become this real everyone talks about? what defines real?
