Define what a "good Christian" is?

What is your definition of a “good Christian”? Is it like someone who faithfully goes to church, who gives to the poor, prays every day, or one who evangelizes? With all the different denominations you can have varying ideals of who is a “good Christian”, but it would be logical to think if there is a “good Christian” there has to be a “bad Christian” which I think most people believe they know better.
