To realize the full meaning of this, let us remember how it was through the body sin entered. 'The woman saw that the tree was good for food,' this was the temptation in the flesh; through this the soul was reached, 'it was a delight to the eyes;' through the soul it then passed into the spirit, 'and to be desired to make one wise.' In John's description of what is in the world (1 John ii. 15), we find the same threefold division, 'the lust of the flesh, the lust of the eyes, and the pride of life.' And the three temptations of Jesus by Satan correspond exactly: he first sought to reach Him through the body, in the suggestion to satisfy His hunger by making bread; the second (see Luke iv.) appealed to the soul, in the vision of the kingdoms of this world and their glory; the third to the spirit, in the call to assert and prove His Divine Sonship by casting Himself down. Even to the Son of God the first temptation came, as to Adam and all in the world, as lust of the flesh, the desire to gratify the natural and lawful appetite of hunger. We cannot note too carefully that it was on a question of eating what appeared good for food that man's first sin was committed, and that that same question of eating to satisfy hunger was the battleground on which the Redeemer's first encounter with Satan took place. It is on the question of eating and drinking what is good and lawful that more Christians than are aware of it are foiled by Satan. To have every appetite of the body under the rule and regulation of the Holy Spirit appears to some needless, to others too difficult. And yet it must be, if the body is to be holy, as God's temple, and we are to glorify Him in our body and our spirit. The first approaches of sin are made through the body: in the body the complete victory will be gained. 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.
