I don’t know how many times the bible says that life isn’t fair, but Solomon makes it perfectly clear in Ecclesiastes 8:14. He writes, “There is a vanity that takes place on earth, that there are righteous people to whom it happens 
according to the deeds of the wicked, and there are wicked people to whom it happens according to the deeds of the righteous. I said that this also is vanity.” John F. Kennedy once summed up his philosophy about life and about political office in one brilliant phrase: “Life isn’t fair, but the government should be.” Now if that is true, how much more is the expectation that God should be fair? We expect justice from government and are confused and disillusioned when we don’t get it. We expect perfect righteousness and justice from God and are outraged when we don’t get it.
Revenge movies are so popular because injustice doesn’t sit well with us. Life really should be fair but it isn’t. As C. S. Lewis points out in Mere Christianity, every human being appeals to a common law of fair play: “That’s my seat—I was there first,” or “Give me a bite of that orange; I gave you a bite of mine.” We’ve all shouted out, “No fair! No fair!” We all have this instinct for fairness. It’s just there and all people in every culture acknowledge its existence by the way they live with each other. Where does this sense of fairness come from? We are created in the image of God. There is in God a value structure which He shares with us. It includes an intuitive awareness of what’s right and what’s wrong. We all long for our perceived sense of justice to be satisfied but we must learn to live without it.
God allows injustice in this life because according to His perfect plan He will one day make everything right. David Jeremiah suggests, “The secret is to remember that this life is just a preparation for the real life that is to come. We are foolish if we think we will ever find heaven on earth.” We often pray what is known as the Lord’s Prayer. We ask, “thy kingdom come, thy will be done on earth as it is in heaven.” The greatest injustice in the world took place on the cross of Calvary. The only absolutely innocent victim of the injustices of man made us a promise before He was crucified. He said, “Let not your heart be troubled; you believe in God, believe also in Me. In My Father’s house are many mansions; if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again and receive you to myself; that where I am, there you may be also (John 14:1–3). He will make everything right.
