(1.) In respect of sanctification. He is the Spirit of holiness, — holy in himself, and the author of holiness in us: he works it in us, Tit. iii. 5, and he persuades us to it, by those motions of his which are not to be 1 Thess. v. 19.quenched. Now, this, in the first place, grieves the Spirit, when he is carrying on in us and for us a work so infinitely for our advantage, and without which we cannot see God, that we should run cross to him, in ways of unholiness, pollution, and defilement. So the connection of the words in the place before mentioned manifests, Eph. iv. 28–31; and thence doth Paul bottom his powerful and most effectual persuasion unto holiness, even from the abode and indwelling of this Holy Spirit with us, 1 Cor. iii. 16, 17. Indeed, what can grieve a loving and tender friend more than to oppose him and slight him when he is most intent about our good, — and that a good of the greatest consequence to us. In this, then, believers make it their business to keep their hearts loyal and their affections chaste to Jesus Christ. They labour instantly not to grieve the Holy Spirit by loose and foolish, by careless and negligent walking, which he hath sent to dwell and abide with them. Therefore shall no anger, wrath, malice, envy, dwell in their hearts; because they are contrary to the holy, meek Spirit of Christ, which he hath given to dwell with them. They attend to his motions, make use of his assistance, improve his gifts, and nothing lies more upon their spirits, than that they may walk worthy of the presence of this holy substitute of the Lord Jesus Christ.
