But the rich, in that he is made low
That is, the rich brother; for there were rich men in the churches in those times, and which James often takes notice of in this epistle. Such an one should rejoice or glory in his lowness, or low estate; in the consideration of the low estate, out of which he was raised, by the good providence of God, and was not owing to any merit of his; and in the low estate into which he may be at present reduced, through the violence of persecution being stripped of all his riches for Christ's sake, of which he might make his boast, and count it his greatest glory; or in that low estate he may quickly expect he shall be brought into, either in the above manner, or by some calamity or another, and at least by death, which will put him upon a level with others: or this may have respect to the temper of his mind, which he has, through the grace of God, and the station he is in, in the church of God, being a brother, and no more than a brother, and upon an equal foot with the meanest member in it; and which yet is matter of rejoicing, that he is one, and that he is so blessed with the grace of humility, as not to lift up himself above others, not to mind high things, but to condescend to men of low estate; and such a deportment the apostle exhorts rich saints unto, from the consideration of the instability and inconstancy of worldly riches.
Because, as the flower of the grass he shall pass
shortly, and suddenly; either he himself by death, or his riches at death, or before, and therefore are not to be gloried in; nor should the possessors of them be proud and haughty and elate themselves with them, but should behave humbly and modestly to their fellow creatures and Christians, as knowing that in a short time they will all be upon a par, or in an equal state; See ( Job 14:2 ) ( Psalms 90:5 Psalms 90:6 ) ( 102:11 ) ( Psalms 103:15 Psalms 103:16 ) . The metaphor here used is enlarged upon in the following verse, for the further illustration of the fickleness, perishing, and transitory nature of earthly enjoyments.
