J. Gresham Machen - Atonement of Christ, Satisfaction for Sin

"If then we ask what is the Biblical doctrine of sin, we observe, in the first place, that according to the Bible all men are sinners.

Well, then, that being so, it becomes important to ask what this sin is which has affected all mankind. Is it just an excusable imperfection; is it something that can be transcended as a man can transcend the immaturity of his youthful years? Or, supposing it to be more than imperfection, supposing it to be something like a definite stain, is it a stain that can easily be removed as writing is erased from a slate?

The Bible leaves us in no doubt as to the answer to these questions. Sin, it tells us, is disobedience to the law of God, and the law of God is entirely irrevocable.

Why is the law of God irrevocable? The Bible makes that plain. Because it is rooted in the nature of God! God is righteous and that is the reason why His law is righteous. Can He then revoke His law or allow it to be disregarded? Well, there is of course no external compulsion upon Him to prevent Him from doing these things. There is none who can say to Him, ‘What doest thou?’ In that sense He can do all things. But the point is, He cannot revoke His law and still remain God. He cannot, without Himself becoming unrighteous, make His law either forbid righteousness or condone unrighteousness. When the law of God says, ‘The soul that sinneth it shall die,’ that awful penalty of death is, indeed, imposed by God’s will; but God’s will is determined by God’s nature, and God’s nature being unchangeably holy the penalty must run its course. God would be untrue to Himself, in other words, if sin were not punished; and that God should be untrue to Himself is the most impossible thing that can possibly be conceived.

Under that majestic law of God man was placed in the estate wherein he was created. Man was placed in a probation, which theologians call the covenant of works. If he obeyed the law during a certain limited period, his probation was to be over; he would be given eternal life without any further possibility of loss. If, on the other hand, he disobeyed the law, he would have death — physical death and eternal death in hell.

Man entered into that probation with every advantage. He was created in knowledge, righteousness and holiness. He was created not merely neutral with respect to goodness; he was created positively good. Yet he fell. He failed to make his goodness an assured and eternal goodness; he failed to progress from the goodness of innocency to the confirmed goodness which would have been the reward for standing the test. He transgressed the commandment of God, and so came under the awful curse of the law.

Under that curse came all mankind. That covenant of works had been made with the first man, Adam, not only for himself but for his posterity. He had stood, in that probation, in a representative capacity; he had stood — to use a better terminology — as the federal head of the race, having been made the federal head of the race by divine appointment. If he had successfully met the test, all mankind descended from him would have been born in a state of confirmed righteousness and blessedness, without any possibility of falling into sin or of losing eternal life. But as a matter of fact Adam did not successfully meet the test. He transgressed the commandment of God, and since he was the federal head, the divinely appointed representative of the race, all mankind sinned in him and fell with him in his first transgression.

Thus all mankind, descended from Adam by ordinary generation, are themselves under the dreadful penalty of the law of God. They are under that penalty at birth, before they have done anything either good or bad. Part of that penalty is the want of the righteousness with which man was created, and a dreadful corruption which is called original sin. Proceeding from that corruption when men grow to years of discretion come individual acts of transgression.

Can the penalty of sin resting upon all mankind be remitted? Plainly not, if God is to remain God. That penalty of sin was ordained in the law of God, and the law of God was no mere arbitrary and changeable arrangement but an expression of the nature of God Himself. If the penalty of sin were remitted, God would become unrighteous, and that God will not become unrighteous is the most certain thing that can possibly be conceived.

How then can sinful men be saved? In one way only. Only if a substitute is provided who shall pay for them the just penalty of God’s law.

The Bible teaches that such a substitute has as a matter of fact been provided. The substitute is Jesus Christ. The law’s demands of penalty must be satisfied. There is no escaping that. But Jesus Christ satisfied those demands for us when He died instead of us on the cross.

I have used the word ‘satisfied’ advisedly. It is very important for us to observe that when Jesus died upon the cross He made a full satisfaction for our sins; He paid the penalty which the law pronounces upon our sin, not in part but in full.

In saying that, there are several misunderstandings which need to be guarded against in the most careful possible way. Only by distinguishing the Scripture doctrine carefully from several distortions of it can we understand clearly what the Scripture doctrine is. I want to point out, therefore, several things that we do not mean when we say that Christ paid the penalty of our sin by dying instead of us on the cross.

In the first place, we do not mean that when Christ took our place He became Himself a sinner. Of course He did not become a sinner. Never was His glorious righteousness and goodness more wonderfully seen than when He bore the curse of God’s law upon the cross. He was not deserving of that curse. Far from it! He was deserving of all praise.

What we mean, therefore, when we say that Christ bore our guilt is not that He became guilty, but that He paid the penalty that we so richly deserved.

In the second place, we do not mean that Christ’s sufferings were the same as the sufferings that we should have endured if we had paid the penalty of our own sins. Obviously they were not the same. Part of the sufferings that we should have endured would have been the dreadful suffering of remorse. Christ did not endure that suffering, for He had done no wrong. Moreover, our sufferings would have endured to all eternity, whereas Christ’s sufferings on the cross endured but a few hours. Plainly then His sufferings were not the same as ours would have been.

In the third place, however, an opposite error must also be warded off. If Christ’s sufferings were not the same as ours, it is also quite untrue to say that He paid only a part of the penalty that was due to us because of our sin. Some theologians have fallen into that error. When man incurred the penalty of the law, they have said, God was pleased to take some other and lesser thing — namely, the sufferings of Christ on the cross — instead of exacting the full penalty. Thus, according to these theologians, the demands of the law were not really satisfied by the death of Christ, but God was simply pleased, in arbitrary fashion, to accept something less than full satisfaction.

That is a very serious error indeed. Instead of falling into it we shall, if we are true to the Scriptures, insist that Christ on the cross paid the full and just penalty for our sin.

The error arose because of a confusion between the payment of a debt and the payment of a penalty. In the case of a debt it does not make any difference who pays; all that is essential is that the creditor shall receive what is owed him. What is essential is that just the same thing shall be paid as that which stood in the bond.

But in the case of the payment of a penalty it does make a difference who pays. The law demanded that we should suffer eternal death because of our sin. Christ paid the penalty of the law in our stead. But for Him to suffer was not the same as for us to suffer. He is God, and not merely man. Therefore if He had suffered to all eternity as we should have suffered, that would not have been to pay the just penalty of the sin, but it would have been an unjust exaction of vastly more. In other words, we must get rid of merely quantitative notions in thinking of the sufferings of Christ. What He suffered on the cross was what the law of God truly demanded not of any person but of such a person as Himself when He became our substitute in paying the penalty of sin. He did therefore make full and not merely partial satisfaction for the claims of the law against us.

Finally, it is very important to observe that the Bible’s teaching about the cross of Christ does not mean that God waited for someone else to pay the penalty of sin before He would forgive the sinner. So unbelievers constantly represent it, but that representation is radically wrong. No, God Himself paid the penalty of sin — God Himself in the Person of God the Son, who loved us and gave Himself for us, God Himself in the person of God the Father who so loved the world as to give His only-begotten Son, God the Holy Spirit who applies to us the benefits of Christ’s death. God’s the cost and ours the marvellous gain! Who shall measure the depths of the love of God which was extended to us sinners when the Lord Jesus took our place and died in our stead upon the accursed tree?" - John Gresham Machen, "The Doctrine of the Atonement"
