That, according as it is written, He that glorieth, let him glory in the Lord.

that, according as it hath been written, 'He who is glorying, in the Lord let him glory.'

That, according as it is written, He that glories, let him glory in the Lord.

in order that it may be as Scripture says, "He who boasts - let his boast be in the Lord."

So that, as it is said in the holy Writings, Whoever has a desire for glory, let his glory be in the Lord.

And so, in the same way, it was written: "Whoever glories, should glory in the Lord."

He that glorieth let him glory in the Lord Mark the end that God has in view in bestowing all things upon us in Christ -- that we may not claim any merit to ourselves, but may give him all the praise. For God does not despoil with the view of leaving us bare, but forthwith clothes us with his glory -- yet on this condition, that whenever we would glory we must go out of ourselves. In short, man, brought to nothing in his own estimation, and acknowledging that there is nothing good anywhere but in God alone, must renounce all desire for his own glory, and with all his might aspire and aim at the glory of God exclusively. This is also more clearly apparent from the context in the writings of the Prophet, from whom Paul has borrowed this testimony; for in that passage the Lord, after stripping all mankind of glory in respect of strength, wisdom, and riches, commands us to glory only in knowing him, (Jeremiah 9:23, 24.) Now he would have us know him in such a way as to know that it is he that exercises judgment, righteousness, and mercy For this knowledge produces in us at once confidence in him and fear of him. If therefore a man has his mind regulated in such a manner that, claiming no merit to himself, he desires that God alone be exalted; if he rests with satisfaction on his grace, and places his entire happiness in his fatherly love, and, in fine, is satisfied with God alone, that man truly "glories in the Lord." I say truly, for even hypocrites on false grounds glory in him, as Paul declares, (Romans 2:17,) when being either puffed up with his gifts, or elated with a base confidence in the flesh, or abusing his word, they nevertheless take his name upon them.

As it is written - This is evidently a quotation made from Jeremiah 9:23-24. It is not made literally; but the apostle has "condensed" the sense of the prophet into a few words, and has retained essentially his idea.
He that glorieth - He that boasts or exults.
In the Lord - Not ascribing his salvation to human abilities, or learning, or rank, but entirely to God. And from this we see:
(1) That the design of the plan of salvation is to exalt God in view of the mind.
(2) that the design is to make us humble; and this is the design also of all his works no less than of the plan of salvation. All just views of the creation tend to produce true humility.
(3) it is an evidence of piety when we are thus disposed to exalt God, and to be humble. It shows that the heart is changed; and that we are truly disposed to honor him.
(4) we may rejoice in God. We have no strength, and no righteousness of which to boast; but we may rejoice in him. He is full of goodness and mercy. He is able to save us. He can redeem us out of the hand of all our enemies. And when we are conscious that we are poor, and feeble, and helpless; when oppressed with a sense of sin, we may rejoice in him as our God; and exult in him as our Saviour and Redeemer. True piety will delight to come and lay everything at his feet; and whatever may be our rank, or talent, or learning, we shall rejoice to come with the temper of the humblest child of poverty, and sorrow, and lack, and to say, "not unto us, not unto us, but unto thy name give glory for thy mercy, and for thy truth's sake," Psalm 115:1.
"Not to our names, thou only just and true,
Not to our worthless names is glory due;
Thy power and grace, thy truth and justice claim.
Immortal honours to thy sovereign name."
Watts.

According as it is written - In Jeremiah 9:23, Jeremiah 9:24 : Thus saith the Lord, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might; let not the rich man glory in his riches; but let him that glorieth glory in this: That he understandeth and knoweth me, that I am the Lord, which exercise loving-kindness, judgment, and righteousness, in the earth. So then, as all good is of and from God, let him that has either wisdom, strength, riches, pardon, holiness, or any other blessing, whether temporal or spiritual, acknowledge that he has nothing but what he has received; and that, as he has cause of glorying (boasting or exultation) in being made a partaker of these benefits and mercies of his Creator and Redeemer, let him boast in God alone, by whom, through Christ Jesus, he has received the whole.
1. This is an admirable chapter, and drawn up with great skill and address. The divided state of the Corinthian Church we have already noticed, and it appears that in these factions the apostle's authority had been set at nought by some, and questioned by many. St. Paul begins his letter with showing his authority; he had it immediately through Christ Jesus himself, by the will of God. And indeed the success of his preaching was a sufficient proof of the Divinity of his call. Had not God been with him he never could have successfully opposed the whole system of the national religion of the Corinthians, supported as it was by the prejudice of the people, the authority of the laws, and the eloquence and learning of their most eminent philosophers. It was necessary, therefore, that he should call the attention of this people to the Divine origin of his mission, that they might acknowledge that the excellency of the power was of God, and not of man.
2. It was necessary also that he should conciliate their esteem, and therefore speak as favourably concerning them as truth would allow; hence he shows them that they were a Church of God, sanctified in Christ Jesus, and called to be saints; that they abounded and even excelled in many extraordinary gifts and graces; and that they were not inferior to any Church of God in any gift. And he shows them that they received all these through God's confirmation of that testimony which he had delivered among them, 1-Corinthians 1:4-7.
3. When he had thus prepared their minds to receive and profit by his admonitions he proceeds to their schisms, which he mentions and reprehends in the most delicate manner, so that the most obstinate and prejudiced could take no offense.
4. Having gained this point, he gently leads them to consider that, as God is the fountain of all good, so their good had all come from him; and that none of them should rest in the gift, but in the giver; nor should they consider themselves as of particular consequence on account of possessing such gifts, because all earthly good is transitory, and those who trust in power, wisdom, or wealth, are confounded and brought to nought; and that they alone are safe who receive every thing as from the hand of God, and, in the strength of his gifts, glorify him who is the donor of all good. He who can read this chapter without getting much profit has very little spirituality in his soul, and must be utterly unacquainted with the work of God in the heart.

That, according as it is written, (b) He that glorieth, let him glory in the Lord.
(b) Let him yield all to God and give him thanks: and so by this place is man's free will beaten down, which the papists so dream about.

That, according as it is written,.... Jeremiah 9:23.
He that glorieth, let him glory in the Lord; not in his own wisdom, riches, and strength; but in Christ, as his wisdom, righteousness, sanctification, and redemption.

glory in . . . Lord-- (Jeremiah 9:23-24) --in opposition to "flesh glorying in His presence" (1-Corinthians 1:29). In contrast to morbid slavish self-abasement, Paul joins with humility the elevating consciousness of our true dignity in Christ. He who glories is to glory in the Lord, not in the flesh, nor in the world.

Let him glory in the Lord - Not in himself, not in the flesh, not in the world. Jeremiah 9:23-24
