What Scripture teaches as to the intimacy of the connection between the body and spirit, physiology confirms. What appear at first merely physical transgressions leave a stain and have a degrading influence on the soul, and through it drag down the spirit. And on the other side, spiritual sins, sins of thought and imagination and disposition, pass through the soul into the body, fix themselves in the nervous constitution, and express themselves even in the countenance and the habits or tendencies of the body. Sin must be combated not only in the region of the spirit: if we are to perfect holiness, we must cleanse ourselves from all defilement of flesh _and_ spirit. 'If through the Spirit ye do make dead the deeds of _the body_, ye shall live.' If we are indeed to be cleansed from sin and made holy unto God, the body, as the outworks, must very specially be secured from the power of Satan and of sin.
And how is this to be done? God has made very special provision for this. Holy Scripture speaks so explicitly of the Holy Spirit, the Spirit that communicates holiness, in connection with the body. At first sight it looks as if the word, your bodies, were simply used as equivalent to, your persons, yourselves. But as the deeper insight into the power of sin in the body, and the need of a deliverance specially there, quickens our perception, we see what is meant by the body being the temple of the Holy Spirit. We notice how very specially it is of sins in the body that Paul speaks as defiling God's holy temple; and how it is through the power of the Holy Ghost in the body that he would have us glorify God. 'Know ye not that _your body_ is the temple of the Holy Ghost: glorify God therefore, in the power of the Holy Spirit, in _your body_.' The Holy Spirit must not only exercise a restraining and regulating influence on the appetites of the body and their gratification, so that they be in moderation and temperance,--this is only the negative side,--but there must be a positively spiritual element, making the exercise of natural functions a service of holy joy and liberty to the glory of God; no longer a threatened hindrance to the life of obedience and fellowship, but a means of grace, a real help to the spiritual life. It is only in a body that is full of the holy life, very entirely possessed of God's Spirit, that this will be the case.
And how can this be obtained? In the true Christian life, self-denial is the path to enjoyment, renunciation to possession, death to life. As long as there is ought that we think we have liberty and power to use or enjoy aright, if we but do so in moderation, we have not yet seen or confessed our own unholiness, or the need of the entire renewing of the Holy Spirit. It is not enough to say, 'Every creature of God is good, if it be received with thanksgiving;' we must remember the addition, 'for it is sanctified by the word and by prayer.' This sanctifying of every creature and its use is a thing as real and solemn as the sanctifying of ourselves. And this will only be where, if need be, we sacrifice the gift and the liberty to use it, until God gives us the power truly to use it to His glory alone. Of one of the most sacred of Divine institutions, marriage, Paul, who so denounces those who would forbid to marry, says distinctly that there may be cases in which a voluntary celibacy may be the surest and acceptable way of being 'holy both in body and spirit.' When to be holy as God is holy indeed becomes the great desire and aim of life, everything will be cherished or given up as it promotes the chief end. The actual and active presence of the Holy Spirit in the life of the body will be the fire that is kept burning continually on the altar.
And how is this to be attained? Of the body as of the spirit it is God, God in Christ, who is our Keeper and our Sanctifier. The guarding of the walls of the city must be entrusted to Him who rules within. 'I am persuaded that He is able to guard my deposit,' to keep that which I have committed to Him, must become as definitely true of the body, and of each of its functions of which we are conscious that it is the occasion of doubt or of stumbling, as it has been of the soul we entrusted to Him for salvation. A fixed deposit in a bank is money given away out of my hands to be kept there: the body or any part of it that needs to be made holy must be a deposit with Jesus. Faith must trust His acceptance and guarding of it; prayer and praise must daily afresh renew the assurance, must confirm the committal of the deposit, and maintain the fellowship with Jesus. Abiding thus in Him and His Holiness, we shall receive, in a life of trust and joy, the power to prove, even in the body, how fully and wholly we are in Him who is made unto us sanctification, how real and true the Holiness of God is in His people.
