1 From whence come wars and fightings among you? come they not hence, even of your lusts that war in your members?
2 Ye lust, and have not: ye kill, and desire to have, and cannot obtain: ye fight and war, yet ye have not, because ye ask not.
3 Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts.
4 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.
5 Do ye think that the scripture saith in vain, The spirit that dwelleth in us lusteth to envy?
6 But he giveth more grace. Wherefore he saith, God resisteth the proud, but giveth grace unto the humble.
7 Submit yourselves therefore to God. Resist the devil, and he will flee from you.
8 Draw nigh to God, and he will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded.
9 Be afflicted, and mourn, and weep: let your laughter be turned to mourning, and your joy to heaviness.
10 Humble yourselves in the sight of the Lord, and he shall lift you up.
11 Speak not evil one of another, brethren. He that speaketh evil of his brother, and judgeth his brother, speaketh evil of the law, and judgeth the law: but if thou judge the law, thou art not a doer of the law, but a judge.
12 There is one lawgiver, who is able to save and to destroy: who art thou that judgest another?
13 Go to now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain:
14 Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.
15 For that ye ought to say, If the Lord will, we shall live, and do this, or that.
16 But now ye rejoice in your boastings: all such rejoicing is evil.
17 Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
Here are cautions against corrupt affections, and love of this world, which is enmity to God. (1-10) Exhortations to undertake no affairs of life, without constant regard to the will and providence of God. (11-17)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.11-17 Our lips must be governed by the law of kindness, as well as truth and justice. Christians are brethren. And to break God's commands, is to speak evil of them, and to judge them, as if they laid too great a restraint upon us. We have the law of God, which is a rule to all; let us not presume to set up our own notions and opinions as a rule to those about us, and let us be careful that we be not condemned of the Lord. "Go to now," is a call to any one to consider his conduct as being wrong. How apt worldly and contriving men are to leave God out of their plans! How vain it is to look for any thing good without God's blessing and guidance! The frailty, shortness, and uncertainty of life, ought to check the vanity and presumptuous confidence of all projects for futurity. We can fix the hour and minute of the sun's rising and setting to-morrow, but we cannot fix the certain time of a vapour being scattered. So short, unreal, and fading is human life, and all the prosperity or enjoyment that attends it; though bliss or woe for ever must be according to our conduct during this fleeting moment. We are always to depend on the will of God. Our times are not in our own hands, but at the disposal of God. Our heads may be filled with cares and contrivances for ourselves, or our families, or our friends; but Providence often throws our plans into confusion. All we design, and all we do, should be with submissive dependence on God. It is foolish, and it is hurtful, to boast of worldly things and aspiring projects; it will bring great disappointment, and will prove destruction in the end. Omissions are sins which will be brought into judgment, as well as commissions. He that does not the good he knows should be done, as well as he who does the evil he knows should not be done, will be condemned. Oh that we were as careful not to omit prayer, and not to neglect to meditate and examine our consciences, as we are not to commit gross outward vices against light!Commentary by Matthew Henry, 1710.
