Isaiah, Prophet of Salvation, Book 6, part 1

The book of Isaiah divides naturally into two main parts. Isaiah 1-39 is part one, showing us the failure of Israel and Judah to fulfill their Old Covenant vow. Isaiah 40-66 shows us the ultimate success of God’s New Covenant vow, or promise. Hence, the first half of Isaiah portrays a sin-sick people being threatened with divine judgment, and it concludes dismally with a promise of exile to Babylon.

Chapter 40 begins a new page with renewed hope, based upon the work of the Holy Spirit, which was sent to ensure God’s success in fulfilling His promise in spite of man’s failure.

Critics have long used this natural division in the book in order to discredit it. Many maintain that the book was written by two different authors, when, in fact, were we to cede that point, our faith is in the fact that God Himself authored the entire book, using men as mere agents of truth. But Isaiah understood the New Covenant while writing the entire book.

The difference is that in the first half of the book, the prophet was inspired to emphasize the Old Covenant aspect of truth, which could only bring the nations to an end. The latter half of the book brings the New Covenant into full view, while the judgments of God largely fade into the background.

It is self-evident that under the Old Covenant God requires repentance in order to be saved. Some do not realize that repentance is also required under the New Covenant. The difference is that the Old Covenant burdens men with the responsibility to repent by the power of their own will; the New Covenant puts the burden upon God to cause men to repent, so that they can be saved. Whoever makes the vow is responsible to fulfill its terms.

Under the Old Covenant, the question is whether or not men would be obedient or, having sinned, would repent for their disobedience. Scripture shows that men repent temporarily but in the end, their morals decay until, except for an overcoming remnant, the nation disintegrates and death reigns. For this reason, Isaiah, the Prophet of Salvation, shows in the first half of his book that salvation cannot be obtained through the Old Covenant.

Under the New Covenant, the question is whether or not God Himself is capable of fulfilling His promises. Is His will powerful enough to overcome the will of men and cause them to repent so that they may be saved? Is God’s sovereignty more powerful than man’s authority? Is the role of the Holy Spirit limited to assisting man fulfill his Old Covenant vow? Or does the Holy Spirit have the power to change the will and heart of man in order to fulfill God’s New Covenant vow to save all mankind? Is God a coach playing under an Old Covenant rule book, or is He a king whose New Covenant word creates reality and prevails in the end?

We are given hints in the first half of the book, but in the last half the prophet boldly proclaims the answer.

The Comforter

Isaiah 40:1 begins,

¹ “Comfort, O comfort My people,” says your God.

The Hebrew word for “comfort” is nacham, and this establishes the Hebrew concept of the Holy Spirit acting as a “Comforter” in John 14:26 KJV,

²⁶ But the Comforter, which is the Holy Ghost, whom the Father will send in My name, He shall teach you all things and bring all things to your remembrance, whatsoever I have said to you.

In a family setting, a comforter is one who brings comfort, especially to a child. Hence, Jesus said in John 14:18 KJV, “I will not leave you comfortless.” The NASB renders this, “I will not leave you as orphans.” The concept is rooted in the concept of the so-called kinsman redeemer, often mistranslated as “avenger of blood.” The head of the family was responsible to bring justice where needed and to represent family members in a court of law. Orphans were often taken in and put under the protection of his covering.

A “comforter” is an advocate in a court of law which helps and instructs a person in the law so that they can make their case before the judge. Jesus said that the Holy Spirit is our Comforter.

More than that, the Hebrew word literally means “to breathe forcibly.” In a sense, it is like a sigh or the hard breathing while giving birth. There is a sense of pity and concern in this word. It is the desire to bring rectification, correction, and a just solution to a problem. Hence, Jesus “breathed” on His disciples to impart to them the Holy Spirit (John 20:22).

The kinsman redeemer actually had two duties. If guilty, a family member needed correction and thus he should repent and submit to divine judgment. If innocent, evidence should be brought forward to establish his innocence. So there were two words (homonyms) that described these distinct situations: nacham and naqam.

Nacham and Naqam

Nacham described “comfort” in the positive sense, while naqam was the “vengeance” of divine judgment. Nacham was designed to acquit the innocent, while naqam was designed to restore the sinner back to a place of forgiveness and honor, usually through restitution payment or, in more serious cases, working off one’s debt (slavery). The kinsman redeemer was not required to side with any sinner, not even a family member. He was first and foremost a servant of God, and this required him to serve the cause of justice, regardless of family ties.

Paul tells us in Romans 12:19,

¹⁹ Never take your own revenge, beloved, but leave room for the wrath of God, for it is written [in Deuteronomy 32:35], “Vengeance is Mine, I will repay,” says the Lord.

Paul quoted Deuteronomy 32:35, where the Hebrew word for “vengeance” is naqam. Paul’s command was given because men’s vengeance is unlike God’s vengeance. Men are motivated by self-interest and their emotions color their judgments. Their intent, more often than not, is to punish rather than to correct and restore. Many Christians misunderstand Paul’s admonition because they think God’s “vengeance” is far more painful than man’s vengeance. In fact, God’s vengeance is designed to restore sinners, so that God may be “all in all” (1 Corinthians 15:28).

In other words, the problem is that man’s vengeance is too harsh and lacks the restorative purpose that are the basis of God’s justice. Man is not more merciful than God; God is far more merciful than man. That is why we are to “leave room for the wrath of God.”

The role of the Holy Spirit, then, is not only to bring comfort but to “convict the world concerning sin” (John 16:8). The Holy Spirit does not set aside justice but uses justice to correct and restore sinners. This is the only lawful way that God can fulfill His vow to save the world.

Words of Kindness

Isaiah 40:2 says,

² “Speak kindly [leb, “heart”] to Jerusalem, and call out to her, that her warfare has ended, that her iniquity has been removed, that she has received of the Lord’s hand double for all her sins.”

The work of the Comforter is to speak to the heart. So the Holy Spirit was not sent merely to change one’s behavior but to change one’s heart, nature, and will. The word of the Holy Spirit is to proclaim that “her warfare has ended.” So Paul tells us in 2 Corinthians 5:18, 19,

¹⁸ Now all these things are from God, who reconciled us to Himself through Christ and gave us the ministry of reconciliation, ¹⁹ namely, that God was in Christ reconciling the world to Himself, not counting their trespasses against them, and He has committed to us the word of reconciliation.

The word (message) of reconciliation is that God has stopped fighting against the world. The message is not a threat but that of reconciliation. An Old Covenant message threatens men with divine judgment for not following Christ; a New Covenant message presents the good news that God Himself intends to fulfill His promise to save the world.

Isaiah tells us that Jerusalem “has received of the Lord’s hand double for all her sins.” This is a reference to the law of restitution in Exodus 22:4, which says that a thief must “pay double” to his victim. So God required men in general and Jerusalem in particular to pay double restitution for their sins. Mystery Babylon, too, is required to pay double (Revelation 18:6).

When a sinner’s sentence is completed, they are to be released by the good news that their time of slavery is accomplished. They are no longer “under the law” but “under grace.” The debt to sin has been paid, and the law has no more power to enslave them. The same law that had enslaved them now gives them grace.
