1 Timothy 6:17

17Command (or charge) those who are rich There being many among Christians who were poor and in a mean condition, it is probable that they were despised (as usually happens) by the rich; and especially this might be common at Ephesus, which was a wealthy city; for in such cities, for the most part, pride is more extensively prevalent. And hence we infer how dangerous is a great abundance of riches. Nor are there wanting good reasons why Paul addresses so severe an admonition to the rich; but it is for the purpose of remedying faults which almost always follow riches in the same manner as the shadow follows the body; and that through the depravity of our natural disposition, for out of the gifts of God we always draw an occasion for sinning.

That they be not haughty, nor hope in the uncertainty of riches He expressly mentions two things against which rich men ought to be on their guard, pride and deceitful hope, of which the former springs from the latter. Accordingly, Paul appears to have added, in the same place, “nor hope in the uncertainty of riches,” in order to point out the source of all pride. For whence comes it, that rich men grow insolent, and take extreme delight in despising others, but because they imagine that they are supremely happy? Vain confidence goes first, and then arrogance follows.

Rich in this world When Paul wishes to correct those faults, he first speaks contemptuously of riches; for the phrase, in this world, is intended to lower them in our esteem. All that is in the world has the taste of its nature; so that it is fading, and quickly passes away. The uncertainty and vanity of the hope that is placed in riches are shewn by him from this consideration, that the possession of them is so transitory that it is like a thing unknown; for, while we think that we hold them, they slip out of our hands in a moment. How foolish is it, therefore, to place our hope in them!

But in the living God He who understands this will find no difficulty in withdrawing his hope from riches; for, if it is God alone who supplies us with everything for the necessary purposes of life, we transfer to riches what is this prerogative, when we place hope in them. Now observe that there is an implied contrast, when he affirms that God giveth abundantly to all. The meaning is, that, although we have a full and overflowing abundance of all things, yet we have nothing but from the blessing of God alone; for it is that blessing alone which imparts to us all that is needful.

Hence it follows, that they are egregiously mistaken, who rely on riches, and do not depend entirely on the blessing of God, in which consists a sufficiency of food and of everything else. Hence also we conclude, that we are forbidden to trust in riches, not only because they belong to the use of mortal life, but likewise because they are nothing but smoke; for we are fed, not by bread only, but by the blessing of God. (Deuteronomy 8:3.) (133)

When he says πλουσίως εἰς ἀπόλαυσιν, abundantly for enjoyment, he describes how kind God is to us, and even to all men, and to the brute beasts; for his kindness extends far and wide beyond our necessity. (Psalms 36:6.)
