To prepare for our new series on the atoning work of God in Christ for the salvation of sinners, I commend the following excerpt from John Murray’s book Redemption: Accomplished & Applied.

Christ’s obedience was vicarious in the bearing of the full judgment of God upon sin, and it was vicarious in the full discharge of the demands of righteousness. His obedience becomes the ground of the remission of sin and of actual justification.

We must not view this obedience in any artificial or mechanical sense. When we speak of Christ’s obedience we must not think of it as consisting simply in formal fulfillment of the commandments of God. What the obedience of Christ involved for him is perhaps nowhere more strikingly expressed than in Hebrews 5:8-10 where we are told that Jesus “learned obedience from the things which he suffered,” that he was made perfect through sufferings, and that “being made perfect he became to all who obey him the author of eternal salvation.” When we examine these passages the following lessons become apparent.

1. It was not through mere incarnation that Christ wrought our salvation and secured our redemption.

2. It was not through mere death that salvation was accomplished.

3. It was not simply through the death upon the cross that Jesus became the author of salvation.

4. The death upon the cross, as the climactic requirement of the price of redemption, was discharged as the supreme act of obedience; it was not death resistlessly inflicted but death upon the cross willingly and obediently wrought.

When we speak of obedience we are thinking not merely of formal acts of accomplishment but also of the disposition, will, determination, and volition which lie back of and are registered in these formal acts. And when we speak of the death of our Lord upon the cross as the supreme act of his obedience we are thinking not merely of the overt act of dying upon the tree but also of the disposition, will, and determinate volition which lay back of the overt act. And, furthermore, we are required to ask the question: whence did our Lord derive the disposition and holy determination to give up his life in death as the supreme act of self-sacrifice and obedience? We are compelled to ask this question because it was in human nature that he rendered this obedience and gave up his life in death. And these texts in the epistle to the Hebrews confirm not only the propriety but the necessity of this question. For in these texts we are distinctly informed that he learned obedience, and he learned this obedience from the things that he suffered. It was requisite that he should have been made perfect through sufferings and become the author of salvation through this perfecting. It was not, of course, a perfecting that required the sanctification from sin to holiness. He was always holy, harmless, undefiled, and separate from sinners. But there was the perfecting of development and growth in the course and path of his obedience – he learned obedience. The heart and mind and will of our Lord had been molded – shall we not say forged? – in the furnace of temptation and suffering. And it was in virtue of what he had learned in that experience of temptation and suffering that he was able, at the climactic point fixed by the arrangements of infallible wisdom and everlasting love, to be obedient unto death, even the death of the cross. It was only as having learned obedience in the path of inerrant and sinless discharge of the Father’s will that his heart and mind and will were framed to the point of being able freely and voluntarily to yield up his life in death upon the accursed tree.

Book of Hebrews 5:5-10

5 Christ did not exalt himself to be made a high priest, but was appointed by him who said to him,

“You are my Son,
today I have begotten you”;

as he says also in another place,

“You are a priest forever,
after the order of Melchizedek.”

In the days of his flesh, Jesus offered up prayers and supplications, with loud cries and tears, to him who was able to save him from death, and he was heard because of his reverence. Although he was a son, he learned obedience through what he suffered. And being made perfect, he became the source of eternal salvation to all who obey him, 10 being designated by God a high priest after the order of Melchizedek.

Westminster Confession of Faith Chapter VIII. 

3. The Lord Jesus, in His human nature thus united to the divine, was sanctified and anointed with the Holy Spirit, above measure, having in Him all the treasures of wisdom and knowledge; in whom it pleased the Father that all fulness should dwell; to the end that, being holy, harmless, undefiled, and full of grace and truth, He might be thoroughly furnished to execute the office of a mediator and surety. Which office He took not unto Himself, but was thereunto called by His Father, who put all power and judgment into His hand, and gave Him commandment to execute the same.

4. This office the Lord Jesus did most willingly undertake; which that He might discharge, He was made under the law, and did perfectly fulfil it, endured most grievous torments immediately in His soul, and most painful sufferings in His body; was crucified, and died; was buried, and remained under the power of death; yet saw no corruption. On the third day He arose from the dead, with the same body in which He suffered, with which also he ascended into heaven, and there sitteth at the right hand of His Father, making intercession, and shall return to judge men and angels at the end of the world.

5. The Lord Jesus, by His perfect obedience, and sacrifice of Himself, which He, through the eternal Spirit, once offered up unto God, hath fully satisfied the justice of His Father; and purchased, not only reconciliation, but an everlasting inheritance in the kingdom of heaven, for all those whom the Father hath given unto Him.
