Ps 6 4Turn, O LORD, and deliver me; save me because of your unfailing love."
If we do not know that God loves us with an unfailing love then we will not know who we are nor will we understand anyone else. The reason is that God decided to legally put a price on everything that He created. And so God demands the perfect payment or He will enact justice in order to get the payment. But our knowledge of ourselves was given in His law as a mirror. In other words if we fulfilled His law then we would have a perfect self knowledge and thus a perfect understanding of every one else.Now you see why we are so complicated and emotional. Because we never measure up to His mirror so that we can be true to ourselves. So what God has done is to give us another righteousness that defines His eternal love for us. In other words because Christ fulfilled the law He fixed our mirror.

Now when we become fixed God reverses the way that we view right and wrong. Instead of Him dealing with us as sinners, He deals with us as perfect in Christ. This is what we call the state of grace. The value of our imperfection is renewed by God acting on behalf of Christ righteousness towards us. So now when we sin, we learn to hate sin because it is not as successful in our knowing ourselves as Christ imputed righteousness, This is why the Apostle said that all His confidence and protection was in Christ.
Its hard for people in this world who want karma to understand that when we do wrong it is covered by someone else. You see they want the justice to be like what they always find when they break the law. They must pay. But you see that desire is why they are slaves to the law. They are blind to our being set free from the law as a way to push the destructive personal vengeance desire away from our being accepted. They do not understand that our acceptance in Christ is the communication that God loves us with an unfailing love. So they do not understand what God does to us as a Father.
