It is evident that this term signifies much more in the New Testament sense than it does in the Old Testament. In the Old Testament it meant but a dedication, a setting apart to a holy use, as in the example of the sanctification of the tabernacle and its contents--the altar and laver, and all the vessels belonging thereto--and Aaron and his sons and their garments. Lev. 8:10-30. In this dispensation of grace it means infinitely more; for in that dispensation it was but an outward and ceremonial work, but now it is an inwrought work, permeating and purifying the affections through and through by the cleansing blood and heavenly fire, and filling the dedicated temple, our body, with the Holy Ghost, as in the example of the early church at Pentecost. The justified believer must meet the conditions of complete separation and exclusive dedication of himself to God, in a sense that no guilty sinner can do. This is the believer's part. He must purify himself. "Every man that hath this hope in him purifieth himself, even as he is pure."--1 John 3:3. "Having therefore these promises, dearly beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God."--2 Cor. 7:1. This brings the believer into the condition where God can fulfill his part. He can now take exclusive possession of the dedicated temple, and sanctify it. "And the very God of peace sanctify you wholly."--1 Thess. 5:23. "And they were all filled with the Holy Ghost."--Acts 2:4. This brings the believer into a more perfect spiritual relationship with God than when simply justified. Sanctification A Bible Doctrine "And now, brethren, I commend you to God, and to the word of his grace, which is able to build you up, and to give you an inheritance among all them which are sanctified." Acts 20:32. "To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me."--Acts 26:18. "Sanctify them through thy truth: thy word is truth.... And for their sakes I sanctify myself, that they also might be sanctified through the truth. Neither pray I for these alone, but for them also which shall believe on me through their word."--John 17:17, 19, 20. "If a man therefore purge himself from these, he shall be a vessel unto honour, sanctified, and meet for the master's use, and prepared unto every good work."--2 Tim. 2:21. "That every one of you should know how to possess his vessel in sanctification and honour."--1 Thess. 4:4. God Our Sanctifier "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. Faithful is he that calleth you, who also will do it."--1 Thess. 5:23, 24.
