But whose hath this world's good, or, If any one has the world's sustenance. He now speaks of the common duties of love, which flow from that chief foundation, that is, when we are prepared to serve our neighbors even to death. He, at the same time, seems to reason from the greater to the less; for he who refuses to alleviate by his goods the want of his brother, while his life is safe and secure, much less would he expose for him his life to danger. Then he denies that there is love in us, if we withhold help from our neighbors. But he so recommends this external kindness, that at the same time he very fitly expresses the right way of doing good, and what sort of feeling ought to be in us. Let this, then, be the first proposition, that no one truly loves his brethren, except he really shews this whenever an occasion occurs; the second, that as far as any one has the means, he is bound so far to assist his brethren, for the Lord thus supplies us with the opportunity to exercise love; the third, that the necessity of every one ought to be seen to, for as any one needs food and drink or other things of which we have abundance, so he requires our aid; the fourth, that no act of kindness, except accompanied with sympathy, is pleasing to God. There are many apparently liberal, who yet do not feel for the miseries of their brethren. But the Apostle requires that our bowels should be opened; which is done, when we are endued with such a feeling as to sympathize with others in their evils, no otherwise than as though they were our own. The love of God Here he speaks of loving the brethren; why then does he mention the love of God? even because this principle is to be held, that it cannot be but that the love of God will generate in us the love of the brethren. [1] And thus God tries our love to him, when he bids us to love men from a regard to himself, according to what is said in Psalm 16:2, "My goodness reaches not to thee, but towards the saints who are on the earth is my will and my care."

Footnotes

1 - "The love of God" here is love of which God is the object, that is, love to God. -- Ed.

But whoso hath this world's good - Has property - called "this world's good," or a good pertaining to this world, because it is of value to us only as it meets our wants this side of the grave; and perhaps also because it is sought supremely by the people of the world. The general meaning of this verse, in connection with the previous verse, is, that if we ought to be willing to lay down our lives for others, we ought to be willing to make those comparatively smaller sacrifices which are necessary to relieve them in their distresses; and that if we are unwilling to do this, we can have no evidence that the love of God dwells in us.
And seeth his brother have need - Need of food, of raiment, of shelter; or sick, and poor, and unable to provide for his own wants and those of his family.
And shutteth up his bowels of compassion from him - The bowels, or "upper viscera," embracing the heart, and the region of the chest generally, are in the Scriptures represented as the seat of mercy, piety, and compassion, because when the mind feels compassion it is that part which is affected. Compare the notes at Isaiah 16:11.
How dwelleth the love of God in him? - How can a man love God who does not love those who bear his image? See the notes at 1-John 4:20. On the general sentiment here, see the notes at James 2:14-16. The meaning is plain, that we cannot have evidence of piety unless we are ready to do good to others, especially to our Christian brethren. See the Matthew 25:45 note; Galatians 6:10 note.

But whoso hath this worlds good - Here is a test of this love; if we do not divide our bread with the hungry, we certainly would not lay down our life for him. Whatever love we may pretend to mankind, if we are not charitable and benevolent, we give the lie to our profession. If we have not bowels of compassion, we have not the love of God in us; if we shut up our bowels against the poor, we shut Christ out of our hearts, and ourselves out of heaven.
This world's good. - Του βιον του κοσμου· The life of this world, i.e. the means of life; for so βιος is often used. See Mark 12:44; Luke 8:43; Luke 15:12, Luke 15:30; Luke 21:4, and other places.
How dwelleth the love of God in him? - That is, it cannot possibly dwell in such a person. Hardheartedness and God's love never meet together, much less can they be associated.

(17) But whoso hath this (p) world's good, and seeth his brother have need, and (q) shutteth up his bowels [of compassion] from him, how dwelleth the love of God in him?
(17) He reasons by comparisons: for if we are bound even to give our life for our neighbours, how much more are we bound to help our brothers' needs with our goods and substance?
(p) Wherewith this life is sustained.
(q) Opens not his heart to him, nor helps him willingly and cheerfully.

But whoso hath this world's good,.... The possessions of this world, worldly substance, the temporal good things of it; for there are some things in it, which are honestly, pleasantly, and profitably good, when used lawfully, and not abused, otherwise they are to the owner's hurt: or "the living of this world"; that which the men of the world give up themselves to, are bent upon, and pursue after; or on which men live, and by which life is maintained, and preserved, and made comfortable in the present state of things; such as meat, drink, apparel, money, houses, lands, &c. The Ethiopic version renders it, "he that hath the government of this world"; as if it pointed at a person that is in some high office of worldly honour and profit, and is both great and rich; but the words are not to be restrained to such an one only, but refer to any man that has any share of the outward enjoyments of life; that has not only a competency for himself and family, but something to spare, and especially that has an affluence of worldly substance; but of him that has not, it is not required; for what a man distributes ought to be his own, and not another's, and in proportion to what he has, or according to his ability:
and seeth his brother have need; meaning, not merely a brother in that strict and natural relation, or bond of consanguinity; though such an one in distress ought to be, in the first place, regarded, for no man should hide himself from, overlook and neglect his own flesh and blood; but any, and every man, "his neighbour", as the Ethiopic version reads, whom he ought to love as himself; and especially a brother in a spiritual relation, or one that is of the household of faith: if he has need; that is, is naked and destitute of daily food, has not the common supplies of life, and what nature requires; and also, whose circumstances are low and mean, though not reduced to the utmost extremity; and if he sees him in this distress with his own eyes, or if he knows it, hears of it, and is made acquainted with it, otherwise he cannot be blameworthy for not relieving him.
And shutteth up his bowels of compassion from him; hardens his heart, turns away his eyes, and shuts his hand; has no tenderness in him for, nor sympathy with his distressed brother, nor gives him any succour: and this shows, that when relief is given, it should be not in a morose and churlish manner, with reflection and reproach, but with affection and pity; and where there is neither one nor the other,
how dwelleth the love of God in him? neither the love with which God loves men; for if this was shed abroad in him, and had a place, and dwelt in him, and he was properly affected with it, it would warm his heart, and loosen his affections, and cause his bowels to move to his poor brother: nor the love with which God is loved; for if he does not love his brother whom he sees in distress, how should he love the invisible God? 1-John 4:20; nor that love which God requires of him, which is to love his neighbour as himself.

this world's good--literally, "livelihood" or substance. If we ought to lay down our lives for the brethren (1-John 3:16), how much more ought we not to withhold our substance?
seeth--not merely casually, but deliberately contemplates as a spectator; Greek, "beholds."
shutteth up his bowels of compassion--which had been momentarily opened by the spectacle of his brother's need. The "bowels" mean the heart, the seat of compassion.
how--How is it possible that "the love of (that is, 'to') God dwelleth (Greek, 'abideth') in him?" Our superfluities should yield to the necessities; our comforts, and even our necessaries in some measure, should yield to the extreme wants of our brethren. "Faith gives Christ to me; love flowing from faith gives me to my neighbor."

But whoso hath this world's good - Worldly substance, far less valuable than life. And seeth his brother have need - The very sight of want knocks at the door of the spectator's heart. And shutteth up - Whether asked or not. His bowels of compassion from him, how dwelleth the love of God in him - Certainly not at all, however he may talk, 1-John 3:18, of loving God.
