17 The highway of the upright is to depart from evil: he that keepeth his way preserveth his soul.

      Note, 1. It is the way of the upright to avoid sin, and every thing that looks like it and leads towards it; and this is a highway marked out by authority, tracked by many that have gone before us, and in which we meet with many that keep company with us; it is easy to find and safe to be travelled in, like a highway, Isa. xxxv. 8. To depart from evil is understanding. 2. It is the care of the upright to preserve their own souls, that they be not polluted with sin, and that by the troubles of the world they may not be put out of the possession of them, especially that they may not perish for ever, Matt. xvi. 26. And it is therefore their care to keep their way, and not turn aside out of it, on either hand, but to press towards perfection. Those that adhere to their duty secure their felicity. Keep thy way and God will keep thee.

      27 An unjust man is an abomination to the just: and he that is upright in the way is abomination to the wicked.

      This expresses not only the innate contrariety that there is between virtue and vice, as between light and darkness, fire and water, but the old enmity that has always been between the seed of the woman and the seed of the serpent, Gen. iii. 15. 1. All that are sanctified have a rooted antipathy to wickedness and wicked people. They have a good will to the souls of all (God has, and would have none perish); but they hate the ways and practices of those that are impious towards God and injurious towards men; they cannot hear of them nor speak of them without a holy indignation; they loathe the society of the ungodly and unjust, and dread the thought of giving them any countenance, but do all they can to bring the wickedness of the wicked to an end. Thus an unjust man makes himself odious to the just, and it is one part of his present shame and punishment that good men cannot endure him. 2. All that are unsanctified have a like rooted antipathy to godliness and godly people: He that is upright in the way, that makes conscience of what he says and does, is an abomination to the wicked, whose wickedness is restrained perhaps and suppressed, or, at least, shamed and condemned, by the uprightness of the upright. Thus Cain did, who was of his father the devil. And this is not only the wickedness of the wicked, that they hate those whom God loves, but their misery too, that they hate those whom them shall shortly see in everlasting bliss and honour, and who shall have dominion over them in the morning, Ps. xlix. 14.
