When we strive to get a little closer to the reality and understand in what sense, and how, Christ represented sin on the cross, we recognise first of all that it was not by His being in any way personally tainted by sin. Indeed, had He Himself been in the faintest degree tainted by sin this would have prevented Him from representing sin on the cross. It was not an actual serpent Moses suspended, but a serpent of brass. It would have been easy to kill one of the snakes that were biting the people, and hang up its body. But it would have been useless. To exhibit one slain snake would only have suggested to the people how many were yet alive. Being itself a real snake, it could have no virtue as a symbol. Whereas the brazen serpent represented all snakes. In it each snake seemed to be represented. Similarly, it was not one out of a number of real sinners that was suspended on the cross, but it was one made “in the likeness of sinful flesh.” So that it was not the sins of one person which were condemned and put an end to there, but sin generally. This was easily intelligible to those who saw the crucifixion. John the Baptist had pointed to Jesus as the Lamb of God that taketh away the sin of the world. How does a Lamb take away sin? Not by instruction, not by example, but by being sacrificed; by standing in the room of the sinner and suffering instead of him. And when Jesus, Himself without sin, hung upon the cross, those who knew His innocence perceived that it was as the Lamb of God He suffered, and that by His death they were delivered.
