St. Paul declares (I Cor. vi 13) that "the body is for the Lord" (Jesus), inasmuch as it is a member of Christ, and "the Lord is for the body;" that is, He purposes to rule and use it as His member, and an instrument for His use, and a mirror for reflecting His glory. "The body is His due, for He assumed the body, and hath therein sanctified us; and we are joined to Him by the resurrection of the body." Thus says Bengel, who adds, "Quanta dignatio!" — "How great an honour!" This honour culminates in the nineteenth verse: "What! know ye not that your body is the temple of the Holy Ghost," His peculiar and perpetual habitation, the last place which He hath chosen for the erection of His altar (Deut. xii. 14). How impressive the injunction which follows, when cleared, as it is in the Revision, of the gloss which diverts the emphasis from the body, the subject under discussion. "Therefore, glorify God in your BODY."
The strongest proof text (1 Thess. v. 23) for the entire sanctification of the body in the present life is found in that prayer of the Apostle Paul in which he makes an exhaustive analysis of man's compound nature, and prays that each specific part may be preserved blameless, after supplicating the very God of peace to sanctify the undivided whole. In his enumeration of parts, Paul descends from the highest and distinctive part, the spirit, the dome of man's being, wherein he is receptive of the Holy Spirit, to the animal soul, containing the passions and appetites in common with the brutes, the second part in the detail which needs the purifying power: thence he goes down to the material foundations of this divine temple and prays for the keeping pure of the sanctified body.
(We have not discussed "the flesh" in the Pauline sense of that term. We have attempted to prove that the body is to be sanctified and the flesh is to be crucified.)
