1 Thess. 5:23, 24, R. V.--"And the God of peace himself sanctify you wholly. . . . Faithful is he that calleth you, who will also do it." God's work is here contrasted with human efforts to achieve the preceding injunctions. Just as in Hebrews 12:2, and Philippians 1:6, the Beginner of faith is also the Finisher; so is it here; consequently the end and aim of every exhortation is but to strengthen faith in God who is able to accomplish these things for us. Of course there is a sense in which the believer is responsible for his progress in the Christian life (Phil. 3:12, 13), yet it is nevertheless true that, after all, it is the divine grace which works all in him (Phil. 2:12, 13). We cannot purify ourselves, but we can yield to God and then the purity will come. The "God of peace," He who reconciles us--is the One who sanctifies us. It is as if the apostle said: "God, by His mighty power will do for you what I, by my admonitions, and you by your own efforts, cannot do." See also John 17:17--"Sanctify them through thy truth." Christ addresses God as the One who is to sanctify the disciples. b) Jesus Christ the Son. Heb. 10:10, R. V.--"By which will we have been sanctified through the offering of the body of Jesus Christ once for all." The death of Jesus Christ separates the believer from sin and the world, and sets him apart as redeemed and dedicated to the service of God. This same truth, namely, the sanctification of the church as based on the sacrificial death of Christ, is set forth in Eph. 5:25, 27--"Christ loved the church, and gave himself up for it; that he might sanctify it." Christ is "made unto us . . . sanctification" (1 Cor. 1:30). See also Heb. 13:12, R. V. c) The Holy Spirit Sanctifies. 1 Pet. 1:2--"Elect according to the foreknowledge of God the Father, through sanctification of the Spirit." 2 Thess. 2:13--". . . . Because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth." The Holy Spirit seals, attests, and confirms the work of grace in the soul by producing the fruits of righteousness therein. It is the Spirit of life in Christ Jesus who gives us freedom from the law of sin and death (Rom. 8:2). He is called the _Holy_ Spirit, not only because He is absolutely holy Himself, but also because he produces that quality of soul-character in the believer. The Spirit is the executive of the God-head for this very purpose. It is the Spirit's work to war against the lusts of the flesh and enable us to bring forth fruit unto holiness (Gal. 5:17-22). How wonderfully this truth is set forth in the contrast between the seventh and eighth chapters of Romans. Note the unsuccessful struggle of the former, and the victory of the latter. Note also that there is no mention of the Holy Spirit in the seventh, while He is mentioned about sixteen times in the eighth chapter. Herein lies the secret of failure and victory, sin and holiness. 2. FROM THE HUMAN SIDE.
