2-е Коринфянам 8:9

For ye know the grace of our Lord Jesus Christ - This was the strongest argument of all; and it is urged home by the apostle with admirable address. Ye know - Ye are acquainted with God's ineffable love in sending Jesus Christ into the world; and ye know the grace - the infinite benevolence of Christ himself. That, though he was rich - The possessor, as he was the creator, of the heavens and the earth; for your sakes he became poor - he emptied himself, and made himself of no reputation, and took upon himself the form of a servant, and humbled himself unto death, even the death of the cross; that ye, through his poverty - through his humiliation and death, might be rich - might regain your forfeited inheritance, and be enriched with every grace of his Holy Spirit, and brought at last to his eternal glory. If Jesus Christ, as some contend, were only a mere man, in what sense could he be said to be rich? His family was poor in Bethlehem; his parents were very poor also; he himself never possessed any property among men from the stable to the cross; nor had he any thing to bequeath at his death but his peace. And in what way could the poverty of one man make a multitude rich? These are questions which, on the Socinian scheme, can never be satisfactorily answered.

ye know the grace--the act of gratuitous love whereby the Lord emptied Himself of His previous heavenly glory (Phi 2:6-7) for your sakes. became poor--Yet this is not demanded of you (Co2 8:14); but merely that, without impoverishing yourselves, you should relieve others with your abundance. If the Lord did so much more, and at so much heavier a cost, for your sakes; much more may you do an act of love to your brethren at so little a sacrifice of self. might be rich--in the heavenly glory which constitutes His riches, and all other things, so far as is really good for us (compare Co1 3:21-22).

For ye know the grace of our Lord Jesus,.... This is a new argument, and a very forcible one to engage to liberality, taken from the wonderful grace and love of Christ, displayed in his state of humiliation towards his people; which is well known to all them that have truly believed in Christ; of this they are not and cannot be ignorant, his love, good will, and favour are so manifest; there are such glaring proofs of it in his incarnation, sufferings, and death, that leave no room for any to doubt of it: that though he was rich; in the perfections of his divine nature, having the fulness of the Godhead in him, all that the Father has, and so equal to him; such as eternity, immutability, infinity and immensity, omnipresence, omniscience, omnipotence, &c. in the works of his hands, which reach to everything that is made, the heavens, the earth, the sea, and all that in them are, things visible and invisible; in his universal empire and dominion over all creature; and in those large revenues of glory, which are due to him from them all; which riches of his are underived from another, incommunicable to another, and cannot be lost: yet for your sakes he became poor; by assuming human nature, with all its weaknesses and imperfections excepting sin; he appeared in it not as a lord, but in the form of a servant; he endured in it a great deal of reproach and shame, and at last death itself; not that by becoming man he ceased to be God, or lost his divine perfections, thought these were much hid and covered from the view of man; and in his human nature he became the reverse of what he is in his divine nature, namely, finite and circumscriptible, weak and infirm, ignorant of some things, and mortal; in which nature also he was exposed to much meanness and outward poverty; he was…

In this and the following chapter Paul is exhorting and directing the Corinthians about a particular work of charity - to relieve the necessities of the poor saints at Jerusalem and in Judea, according to the good example of the churches in Macedonia, Rom 15:26. The Christians at Jerusalem, through war, famine, and persecution, had become poor, many of them had fallen into decay, and perhaps most of them were but poor when they first embraced Christianity; for Christ said, "The poor receive the gospel." Now Paul, though he was the apostle of the Gentiles, had a fonder regard, and kind concern, for those among the Jews who were converted to the Christian faith; and, though many of them had not so much affection to the Gentile converts as they ought to have had, yet the apostle would have the Gentiles to be kind to them, and stirred them up to contribute liberally for their relief. Upon this subject he is very copious, and writes very affectingly. In this eighth chapter he acquaints the Corinthians with, and commends, the good example of the Macedonians in this work of charity, and that Titus was sent to Corinth to collect their bounty (Co2 8:1-6). He the proceeds to urge this duty with several cogent arguments (Co2 8:7-15), and commends the persons who were employed in this affair (Co2 8:16-24).

8:9 The model for generous giving is the Lord himself, who was rich in the Father’s presence (John 17:5, 24) yet became poor by accepting a human existence and death on the cross (see Phil 2:6-11). By that self-giving sacrifice, he could make people rich with the blessings of salvation.
