Jeremiah 23:6

It then follows, that Judeah shall be saved in the days of this king. By days we are not to understand the life only of Christ, which he lived in this world, but that perpetuity of which Isaiah speaks, when in wonder he asks,

“His age who shall declare?” (Isaiah 53:8;)

for he died once, that he might live to God, according to what Paul says. (Romans 6:10.) It was then but a short beginning of life when Christ was manifested in the world, and held converse with men; but his life is to continue for ever. It is then the same thing as though the Prophet had said, that when Christ came and descended from the Father, the Church would be saved.

If it be now asked, “How long shall it be saved?” the answer is, “As long as the King himself shall continue; and there is no end to his kingdom.” It follows then that the salvation of the Church will be for ever. This is the import of the whole.

Now, though the Prophet speaks of the deliverance of the people, there is yet no doubt but that he especially sets forth what properly belongs to the kingdom of Christ. He is set over us as a king, that he might be our Savior; and his salvation, though it extends to our bodies, ought yet to be viewed as properly belonging to our souls; for the kingdom of Christ is spiritual, and so is everything connected with it. Hence, when the Prophet says that saved would be Judah, it is the same thing as though he promised that the happiness of the Church would be real and solid under Christ.

He adds, Israel shall dwell in confidence; for in a happy life the first thing is, that we possess tranquil and quiet minds; for tranquillity has not been without reason commended by the ancients. When all things which men covet are heaped together, and what they think necessary for happiness, they yet cannot be otherwise than miserable if their minds are not in a right state. It is not then without cause that tranquillity is added, when mention is made of salvation. And experience itself teaches us, that we have no salvation, unless we, relying on Christ the Mediator, have peace with God, as Paul also mentions it as the fruit of faith, and shews that we cannot otherwise but be always miserable: we have peace, he says, with God. (Romans 5:1.) He hence also concludes that our very miseries are a help to our salvation; for afflictions prove patience, patience exercises hope, and hope never makes us ashamed; and the proof of this is added, because God thus really shews that he is present with us.

We hence see how fitly the Prophet connects tranquillity of mind with happiness. Moreover it is certain that we do not yet enjoy either salvation or peace, such as are here promised; but let us learn by faith what salvation is, and also what is rest even in the midst of the agitations to which we are continually exposed; for we recumb on God when we cast our anchor in heaven. Since, then, the Prophet says here that Judah would be saved and that Israel would be in a tranquil state, let us know that he includes the whole kingdom of Christ from the beginning to the end, and that therefore it is no wonder that he speaks of that perfect happiness, the first fruits of which now only appear.

He then adds, And this is the name by which they shall call him, Jehovah our Righteousness By these words the Prophet shews more clearly that he speaks not generally of David’s posterity, however excellent they may have been, but of the Mediator, who had been promised, and on whom depended the salvation of the people; for he says that this would be his name, Jehovah our Righteousness (81)

Those Jews, who seem more modest than others, and dare not, through a dogged pertinacity, to corrupt this passage, do yet elude the application of this title to Christ, though it be suitable to him; for they say that the name is given to him, because he is the minister of God’s justice, as though it was said, that whenever this king appeared all would acknowledge God’s justice as shining forth in him. And they adduce other similar passages, as when Moses calls the altar, “Jehovah my banner,” or my protection. (Exodus 17:15.) But there is no likeness whatever between an altar and Christ. For the same purpose they refer to another passage, where it is said,

“And this is the name by which they shall call Jerusalem,
Jehovah our peace.” (Ezekiel 48:35)

Now Moses meant nothing else than that the altar was a monument of God’s protection; and Ezekiel only teaches, that the Church would be as it were a mirror in which God’s mercy would be seen, as it would shine forth then, as it were, visibly. But this cannot for the same reason be applied to Christ; he is set forth here as a Redeemer, and a name is given to him, — what name? the name of God. But the Jews object and say, that he was God’s minister, and that it might therefore be in a sense applied to him, though he was no more than a man.

But all who without strife and prejudice judge of things, can easily see that this name is suitably applied to Christ, as he is God; and the Son of David belongs to him as he is man. The Son of David and Jehovah is one and the same Redeemer. Why is he called the Son of David? even because it was necessary that he should be born of that family. Why then is he called Jehovah? we hence conclude that there is something in him more excellent than what is human; and he is called Jehovah, because he is the only-begotten Son of God, of one and the same essence, glory, eternity, and divinity with the Father.

It hence appears evident to all who judge impartially and considerately, that Christ is set forth here in his twofold character, so that the Prophet brings before us both the glory of his divinity and the reality of his humanity. And we know how necessary it was that Christ should come forth as God and man; for salvation cannot be expected in any other way than from God; and Christ must confer salvation on us, and not only be its minister. And then, as he is God, he justifies us, regenerates us, illuminates us into a hope of eternal life; to conquer sin and death is doubtless what only can be effected by divine power. Hence Christ, except he was God, could not have performed what we had to expect from him. It was also necessary that he should become man, that he might unite us to himself; for we have no access to God, except we become the friends of Christ; and how can we be so made, except by a brotherly union? It was not then without the strongest reason, that the Prophet here sets Christ before us both as a true man and the Son of David, and also as God or Jehovah, for he is the only-begotten Son of God, and ever the same in wisdom and glory with the Father, as John testifies in Jeremiah 17:5.

We now then perceive the simple and real meaning of this passage, even that God would restore his Church, because what he had promised respecting a Redeemer stood firm and inviolable. Then he adds what this Redeemer would be and what was to be expected from him; he declares that he would be the true God and yet the Son of David; and he also bids us to expect righteousness from him, and everything necessary to a full and perfect happiness.

But by saying, God our righteousness, the Prophet still more fully shews that righteousness is not in Christ as though it were only his own, but that we have it in common with him, for he has nothing separate from us. God, indeed, must ever be deemed just, though iniquity prevailed through the whole world; and men, were they all wicked, could do nothing to impugn or mar the righteousness of God. But yet God is not our righteousness as he is righteous in himself, or as having his own peculiar righteousness; and as he is our judge, his own righteousness is adverse to us. But Christ’s righteousness is of another kind: it is ours, because Christ is righteous not for himself, but possesses a righteousness which he communicates to us. We hence see that the true character of Christ is here set forth, not that he would come to manifest divine justice, but to bring righteousness, which would avail to the salvation of men, For if we regard God in himself, as I have said, he is indeed righteous, but is not our righteousness. If, then, we desire to have God as our righteousness, we must seek Christ; for this cannot be found except in him. The righteousness of God has been set forth to us in Christ; and all who turn away from him, though they may take many circuitous courses, can yet never find the righteousness of God. Hence Paul says that he has been given or made to us righteousness, — for what end? that we might be made the righteousness of God in him. (1 Corinthians 1:30.) Since, then, Christ is made our righteousness, and we are counted the righteousness of God in him, we hence learn how properly and fitly it has been said that he would be Jehovah, not only that the power of his divinity might defend us, but also that we might become righteous in him, for he is not only righteous for himself, but he is our righteousness.
