If you ever get the idea that God is supposed to be fair, I have some Truth you need to know. God is not fair; God is just. God doesn’t owe us anything. He is a God of mercy, and we can never plead for mercy until we understand the justice of God.
A lady went to a photographer to have her picture made. When she saw it, she didn’t like it, so she asked the photographer to take her picture again. He said, “Well, lady, what’s wrong with it?” She said, “It doesn’t do me justice.” He looked at it, then looked at her and said, “Lady, you don’t need justice; what you need is mercy.”
If you’ve never come to the place where you see yourself as a sinner lost before Almighty God and cried out to Him for mercy, then you’ve never been saved. You may waltz down somebody’s church aisle and join the church, but have you thrown yourself on the mercy seat of the throne of God? Have you said, “Lord God, be merciful to me, a sinner”?
Listen to Romans 3:21-26. The Living Bible renders it so clearly:   “But now God has shown us a way to be made right with him without keeping the requirements of the law, as was promised in the writings of Moses and the prophets long ago. We are made right with God by placing our faith in Jesus Christ. And this is true for everyone who believes, no matter who we are. For everyone has sinned; we all fall short of God’s glorious standard. Yet God, with undeserved kindness, declares that we are righteous. He did this through Christ Jesus when he freed us from the penalty for our sins. For God presented Jesus as the sacrifice for sin. People are made right with God when they believe that Jesus sacrificed his life, shedding his blood. This sacrifice shows that God was being fair when he held back and did not punish those who sinned in times past, for he was looking ahead and including them in what he would do in this present time. God did this to demonstrate his righteousness, for he himself is fair and just, and he declares sinners to be right in his sight when they believe in Jesus.”
