The Surety's Work

How is Job's condition, a type of leprosy, a picture of our sin before the LORD? How do most people try to get by in their sin by avoiding Christ and covering it in their own way? Why was everything about Job exposed? Who is it saying, 'I've found a Ransom'? What is the difference between an atonement and reconciliation according to Scripture? Where is the imputed righteousness rendered to each sinner that Christ died for? How is salvation a legal matter between God and His Son? Does ransom here mean a debt cancelled or paid in full? What does it mean that Christ 'sat down'? Was the law and justice satisfied when you believed or when Christ died? Why did God Himself have to pay the ransom? Who is the Messenger of the Covenant?
