Fairness is the quality of making judgments that are free from discrimination or manipulation. Justice is an action that is morally right and fair. I think the difference is that fairness is about having a proper perspective and justice is about having the right thing done. Someone who is fair is seen as just, but sometimes justice can be cruel and seem not fair. GOD IS JUST MEANS that He is fair and impartial. It also means that He hates the ill-treatment and oppression of people and of nature, which He has created. He hates lying, cheating, and other forms of mistreatment of others. The fact that God is just means that He can and will judge between right and wrong and He will administer justice in accordance with His standards.
