What is Being a Christian?

Who are we? Why do we call ourselves Christians if we don't have anything different with us then everyone else? Well I thought about this lots and again I'm not going to give you an answer but what makes us different? When I was younger I believed it was because we didn't sin but the rest of the world did. But that was flat out wrong if thats what a Christian is I'm not one I sin ALL the time. So I looked it up and Christian means Christ like. Well...that should explain it right but we are not the same as Jesus we sin but Jesus paid the price so that we could be forgiven of our sins and make us more like Christ. So is that it does being a Christian just mean that you ask God for forgiveness all the time? For me there were always people in my life that I thought were amazing Christians and if you have anyone you feel that way about ask yourself or even them why you see God in them. What is it to be Christ like?
