Sanctification (2), the Work of the Triune God - John Colquhoun

Continuing with excerpts on sanctification from John Colquhoun's sermon:

3d, As to the subjects of sanctification, they who are sanctified are elect sinners. This inestimable blessing belongs to them and to none else. "God hath from the beginning chosen you to salvation, through sanctification of the Spirit, and belief of the truth," 2 Thess. ii. 13. And in another place, "According as he hath chosen us in him before the foundation of the world, that we should be holy," etc...

Thus the whole man is the subject of sanctification. As in union with the first Adam, the old man possessed every faculty and member, so, when united to the second Adam, the new man in his turn possesses the whole. "The very God of peace sanctify you wholly; and I pray God your whole spirit, and soul, and body, be preserved blameless unto the coming of our Lord Jesus Christ," 1 Thess. v. 23. Though, however, every part be sanctified, yet no part is perfectly sanctified in this world. There is no spiritual grace implanted without having corruption in the same faculty struggling against it, Gal. v. 17...

4th, Sanctification is both a privilege and a duty. — It is a privilege, as graciously promised in the Gospel. " I will put my Spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them," Ezek. xxxvi. 27. it is a duty, as required in the law. "Make you a new heart, and a new spirit: purify your hearts, ye double-minded." It is a privilege, for it is purchased for us, given to us, and wrought in us by the sanctifying Spirit. As a duty, we study it, and attain to higher degrees of it. We daily receive it out of the fullness of Christ, by faith in his death, resurrection, and promise...

5th, The causes of sanctification are various. — The impulsive cause of it is the sovereign grace, or good pleasure of God, Phil. ii. 13. ; Tit. iii. 5. The blessing of sanctification is of more value than all the treasures and kingdoms of the world, and yet it is freely bestowed. God sanctifies none because of any previous good qualities in them, for before it they have none; but merely from his sovereign grace. Nay, he often overlooks persons of the sweetest natural tempers, and bestows sanctifying grace on the most rugged and stubborn. O the freeness of his sovereign grace!... 

The meritorious cause of it is the blood of Christ, who, through the eternal Spirit, offered himself without spot to God. "Wherefore Jesus also, that he might sanctify the people with his own blood, suffered without the gate," Heb. xiii. 12. This infinitely precious blood, as it has an atoning, so it has a sanctifying efficacy. It purges the conscience from dead works to serve the living God. — It has also a regulating cause, namely, the holy law. It is denominated holiness, because it has a resemblance to the holy nature of God, and righteousness, because it corresponds to his law as a rule of duty. The instrumental cause of it is saving faith, Acts xv. 9.

6th, It is initial and progressive. — Initial sanctification is the same as regeneration, or the renewing in effectual calling. It is the sowing of the spiritual seed of grace, in the heart of the dead sinner. "Whosoever is born of God doth not commit sin; for his seed remaineth in him," 1 John iii. 9. In initial sanctification, the Spirit of Christ enters the heart with all his train of spiritual graces, and implants them there. He introduces spiritual life, impresses the soul with the image of God, creates new inclinations and motions, or, in other words, forms the new creature. This he does in an instant. How inexpressibly happy is the soul that is favoured with it! In this initial sanctification, the sinner is entirely passive. — Progressive sanctification is the Holy Spirit's carrying on the work already begun, till he brings it to perfection. Initial sanctification introduces a perfection of the parts of the new creature; progressive, is the gradual advancing of each of those parts to perfection, till this new creature grows to a perfect man, unto the measure of the stature of the fulness of Christ. In progressive sanctification, the body of sin is more and more mortified; the image of Satan is more and more defaced; the graces of the Holy Spirit are gradually strengthened; and the image of the second Adam is more distinctly expressed...
