17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
English Standard Version
17 For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh, for these are opposed to each other, to keep you from doing the things you want to do.
17 For there is a root of sinful self-interest in us that is at odds with a free spirit, just as the free spirit is incompatible with selfishness. These two ways of life are antithetical, so that you cannot live at times one way and at times another way according to how you feel on any given day.
New King James Version
17 For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish.
New Living Translation
17 The sinful nature wants to do evil, which is just the opposite of what the Spirit wants. And the Spirit gives us desires that are the opposite of what the sinful nature desires. These two forces are constantly fighting each other, so you are not free to carry out your good intentions.
If it be our care to act under the guidance and power of the blessed Spirit, though we may not be freed from the stirrings and oppositions of the corrupt nature which remains in us, it shall not have dominion over us. Believers are engaged in a conflict, in which they earnestly desire that grace may obtain full and speedy victory. And those who desire thus to give themselves up to be led by the Holy Spirit, are not under the law as a covenant of works, nor exposed to its awful curse. Their hatred of sin, and desires after holiness, show that they have a part in the salvation of the gospel. The works of the flesh are many and manifest. And these sins will shut men out of heaven. Yet what numbers, calling themselves Christians, live in these, and say they hope for heaven! The fruits of the Spirit, or of the renewed nature, which we are to do, are named. And as the apostle had chiefly named works of the flesh, not only hurtful to men themselves, but tending to make them so to one another, so here he chiefly notices the fruits of the Spirit, which tend to make Christians agreeable one to another, as well as to make them happy. The fruits of the Spirit plainly show, that such are led by the Spirit. By describing the works of the flesh and fruits of the Spirit, we are told what to avoid and oppose, and what we are to cherish and cultivate; and this is the sincere care and endeavour of all real Christians. Sin does not now reign in their mortal bodies, so that they obey it, Romans 8:5. We must set ourselves in earnest to mortify the deeds of the body, and to walk in newness of life. Not being desirous of vain-glory, or unduly wishing for the esteem and applause of men, not provoking or envying one another, but seeking to bring forth more abundantly those good fruits, which are, through Jesus Christ, to the praise and glory of God.
