{3} Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God.

(3) Another reason why such unbridled lusts and pleasures are utterly to be condemned, that is, because he who gives himself to the world divorces himself from God, and breaks the band of that holy and spiritual marriage.

People's New Testament

4:4 Ye adulterers and adulteresses. Adulterous spouses of Christ who commit fornication with the world. It is spiritual adultery that is meant.

The friendship of the world is enmity with God. Since the prince of this world is opposed to Christ and the spirit of the world is also opposed, one cannot love the ways of the world and love God also. Ye cannot serve God and mammon (Mt 6:24).

Wesley's Notes

4:4 Ye adulterers and adulteresses - Who have broken your faith with God, your rightful spouse. Know ye not that the friendship or love of the world - The desire of the flesh, the desire of the eye, and the pride of life, or courting the favour of worldly men, is enmity against God? Whosoever desireth to be a friend of the world - Whosoever seeks either the happiness or favour of it, does thereby constitute himself an enemy of God; and can he expect to obtain anything of him?

Jamieson-Fausset-Brown Bible Commentary

4. The oldest manuscripts omit "adulterers and," and read simply, "Ye adulteresses." God is the rightful husband; the men of the world are regarded collectively as one adulteress, and individually as adulteresses.

the world-in so far as the men of it and their motives and acts are aliens to God, for example, its selfish "lusts" (Jas 4:3), and covetous and ambitious "wars and fightings" (Jas 4:1).

enmity-not merely "inimical"; a state of enmity, and that enmity itself. Compare 1Jo 2:15, "love . the world . the love of the Father."

whosoever . will be-The Greek is emphatic, "shall be resolved to be." Whether he succeed or not, if his wish be to be the friend of the world, he renders himself, becomes (so the Greek for "is") by the very fact, "the enemy of God." Contrast "Abraham the friend of God."

Matthew Henry's Concise Commentary

4:1-10 Since all wars and fightings come from the corruptions of our own hearts, it is right to mortify those lusts that war in the members. Wordly and fleshly lusts are distempers, which will not allow content or satisfaction. Sinful desires and affections stop prayer, and the working of our desires toward God. And let us beware that we do not abuse or misuse the mercies received, by the disposition of the heart when prayers are granted When men ask of God prosperity, they often ask with wrong aims and intentions. If we thus seek the things of this world, it is just in God to deny them. Unbelieving and cold desires beg denials; and we may be sure that when prayers are rather the language of lusts than of graces, they will return empty. Here is a decided warning to avoid all criminal friendships with this world. Worldly-mindedness is enmity to God. An enemy may be reconciled, but enmity never can be reconciled. A man may have a large portion in things of this life, and yet be kept in the love of God; but he who sets his heart upon the world, who will conform to it rather than lose its friendship, is an enemy to God. So that any one who resolves at all events to be upon friendly terms with the world, must be the enemy of God. Did then the Jews, or the loose professors of Christianity, think the Scripture spake in vain against this worldly-mindedness? or does the Holy Spirit who dwells in all Christians, or the new nature which he creates, produce such fruit? Natural corruption shows itself by envying. The spirit of the world teaches us to lay up, or lay out for ourselves, according to our own fancies; God the Holy Spirit teaches us to be willing to do good to all about us, as we are able. The grace of God will correct and cure the spirit by nature in us; and where he gives grace, he gives another spirit than that of the world. The proud resist God: in their understanding they resist the truths of God; in their will they resist the laws of God; in their passions they resist the providence of God; therefore, no wonder that God resists the proud. How wretched the state of those who make God their enemy! God will give more grace to the humble, because they see their need of it, pray for it are thankful for it, and such shall have it. Submit to God, ver. 7. Submit your understanding to the truth of God; submit your wills to the will of his precept, the will of his providence. Submit yourselves to God, for he is ready to do you good. If we yield to temptations, the devil will continually follow us; but if we put on the whole armour of God, and stand out against him, he will leave us. Let sinners then submit to God, and seek his grace and favour; resisting the devil. All sin must be wept over; here, in godly sorrow, or, hereafter, in eternal misery. And the Lord will not refuse to comfort one who really mourns for sin, or to exalt one who humbles himself before him.
