The last book of the Bible opens with the words: “The revelation of Jesus Christ,” and from these words it derives its title: “The Revelation.” In this book John deals largely with the return of Christ in glory to judge and reign on earth at His 2nd coming. 2 Thes. 1:7-8 tells us that one day “the Lord Jesus shall be revealed from heaven… in flaming fire taking vengeance on them that… obey not the gospel of our Lord Jesus Christ.” This is what the book of the Revelation is basically about.

Under the terms of the Apostle Paul's "gospel of the grace of God" (Acts 20:24) in this day of "the dispensation of the grace of God" (Eph 3:2), it is only by the pure grace of God "in Christ" that believers may stand "holy & blameless" (Eph 1:4) before Him. Believers then "become rooted and grounded 'in Christ," growing in the knowledge and grace of God. We "grow up into him (Christ) in all things..." (Eph 4:15).

I've taken the title "Sanctification of the Spirit" from Paul's words in 2Thes 2:13. "…God hath from the beginning chosen you to (unto) salvation through Sanctification of The Spirit …"

For many the Bible doctrine of sanctification is thought to be a negative matter; "Don't do this" and "Don't do that." Paul here speaks against this form of false sanctification as fostered by the "doctrines of men," while not being of God.
