James 1:10

10But the rich, in that he is made low, or, in his lowness. He has mentioned the particular for the general; for this admonition pertains to all those who excel in honor; or in dignity, or in any other external thing. He bids them to glory in their lowness or littleness, in order to repress the haughtiness of those who are usually inflated with prosperity. But he calls it lowness, because the manifested kingdom of God ought to lead us to despise the world, as we know that all the things we previously greatly admired, are either nothing or very little things. For Christ, who is not a teacher except of babes, checks by his doctrine all the haughtiness of the flesh. Lest, then, the vain joy of the world should captivate the rich, they ought to habituate themselves to glory in the casting down of their carnal excellency. (103)

As the flower of the grass. Were any one to say that James alludes to the words of Isaiah, I would not much object; but I cannot allow that he quotes the testimony of the Prophet, who speaks not only of the things of this life and the fading character of the world, but of the whole man, both body and soul; [Isaiah 40:6;] but here what is spoken of is the pomp of wealth or of riches. And the meaning is, that glorying in riches is foolish and preposterous, because they pass away in a moment. The philosophers teach the same thing; but the song is sung to the deaf, until the ears are opened by the Lord to hear the truth concerning the eternity of the celestial kingdom. Hence he mentions brother; intimating that there is no place for this truth, until we are admitted into the order of God’s children.
