VI. The work of apostleship, we are told by a prime labourer in it, was to turn people "from darkness to light, and from the power of Satan unto God." (Acts, xxvi. 18.) That is, instead of yielding to the temptations and motions of Satan, who is the prince of darkness or wickedness, the one being a metaphor to the other, by whose power their understandings were obscured, and their souls held in the service of sin, they should turn their minds to the appearance of Christ, the Light and Saviour of the world; who by his light shines in their souls, and thereby gives them a sight of their sins, and discovers every temptation and motion in them unto evil, and reproves them when they give way thereunto; that so they might become the children of light, and walk in the path of righteousness. And for this blessed work of reformation did Christ endue his apostles with his spirit and power, that so men might not longer sleep in a security of sin and ignorance of God, but awake to righteousness, that the Lord Jesus might give them life; that is, that they might leave off sinning, deny themselves the pleasure of wickedness, and, by true repentance, turn their hearts to God in well doing, in which is peace. And truly God so blessed the faithful labours of these poor mechanics, yet his great ambassadors to mankind, that in a few years many thousands that had lived without God in the world, without a sense or fear of him, lawlessly, very strangers to the work of his Spirit in their hearts, being captivated by fleshly lusts, were inwardly struck and quickened by the word of life, and made sensible of the coming and power of the Lord Jesus Christ as a judge and lawgiver in their souls, by whose holy light and spirit the hidden things of darkness were brought to light and condemned, and pure repentance from those dead works begotten in them, that they might serve the living God in newness of spirit. So that thenceforward they lived not to themselves, neither were they carried away of those former divers lusts, by which they had been seduced from the true fear of God; but "the law of the spirit of life," (Rom. viii. 2,) by which they overcame the law of sin and death, was their delight, and therein did they meditate day and night. Their regard towards God was not taught by the precepts of men any longer, (Isaiah, xxix. 13,) but from the knowledge they had received by his own work and impressions in their souls. They had quitted their old masters, the world, the flesh, and the devil, and delivered up themselves to the holy guidance of the grace of Christ, that taught them to "deny ungodliness and the world's lusts, and to live soberly, righteously, and godly in this present life:" (Tit. ii. 11, 12:) this is the cross of Christ indeed, and here is the victory it gives to them that take it up; by this cross they died daily to the old life they had lived, and by holy watchfulness against the secret motions of evil in their hearts they crushed
