The main difference between being fair and being just is the separation of God and humans. Fairness has to do with the morals and ideals that humans hold to be important. Although all morals humans have come from God, the interpretation of these morals are what creates the idea of fairness. Humans believe that everything should be fair and equal, but that is different from just. Justice is conformity to God's character, and a lot of the things that people want to be "fair" these days are not pleasing to God, nor are they just. They are fair in the eyes of the people. The concept of fairness is man-made. Complete fairness is impossible to achieve because of human sin, but nevertheless, Americans keep trying to come up with new ways to make the U.S. to seem a little fairer whether by protesting about something, taking it to court, or downright ignoring laws that make their beliefs of something "unfair". People are forgetting that the end of all goals is to create and maintain justice. When you conform to God's character and see things from the perspective of his point of view, you start to realize that with justice comes "fairness".
