Again, in Acts xxvi. 18, the converted Gentiles are spoken of as "receiving forgiveness of sins and an inheritance among them which _are_ sanctified by faith." Here, faith is the instrument by which we are said to be sanctified, because it connects us with Christ. The very moment the sinner believes on the Lord Jesus Christ he becomes linked to Him. He is made one with Him, complete in Him, accepted in Him. This is true sanctification and justification. It is not a process. It is not a gradual work. It is not progressive. The word is very explicit. It says, "them which _are_ sanctified by _faith_ which is in me." It does not say, "which _shall be_ sanctified," or, "which are being sanctified." If such were the doctrine it would have been so stated. No doubt, the believer grows in the knowledge of this sanctification, in his sense of its power and value, its practical influence and results, the experience and enjoyment of it. As "the truth" pours its divine light upon his soul, he enters into a more profound apprehension of what is involved in being "set apart" for Christ, in the midst of this evil world. All this is blessedly true; but the more its truth is seen, the more clearly we shall understand that sanctification is not merely a progressive work, wrought in us by the Holy Spirit, but that it is one result of our being linked to Christ, by faith, whereby we become partakers of all that He is. This is an immediate, a complete, and an eternal work. "Whatsoever God doeth, it shall be forever: nothing can be put to it, nor anything taken from it." (Eccles. iii. 14.) Whether He justifies or sanctifies, "it shall be forever." The stamp of eternity is fixed upon every work of God's hand: "nothing can be put to it," and, blessed be His name, "nothing can be taken from it." There are passages which present the subject in another aspect,--the _practical result_ in the believer of his sanctification in Christ, and which may require fuller consideration hereafter. In 1 Thess. v. the apostle prays for the saints whom he addresses, "And 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." Here, the word is applied to a sanctification admitting of degrees. The Thessalonians had, along with all believers, a perfect sanctification in Christ; but as to the practical enjoyment and display of this, it was only accomplished in part, and the apostle prays that they may be wholly sanctified.
