Walk in the Spirit, and ye shall not fulfil the lust of the flesh.'--Gal. 5:16.
WE are not to suppose that the Apostle here uses the familiar contrast of spirit and flesh to express simply different elements of human nature. Without entering here on questions for which a sermon is scarcely a suitable vehicle of discussion, it may be sufficient for our present purpose to say that, as usually, when employing this antithesis the Apostle means by Spirit the divine, the Spirit of God, which he triumphed in proclaiming to be the gift of every believing soul. The other member of the contrast, flesh,' is similarly not to be taken as equivalent to body, but rather as meaning the whole human nature considered as apart from God and kindred with earth and earthly things. The flesh, in its narrower sense, is no doubt a predominant part of this whole, but there is much in it besides the material organisation. The, ethics of Christianity suffered much harm and were degraded into a false and slavish asceticism for long centuries, by monastic misunderstandings of what Paul meant by the flesh, but he himself was too clear-sighted and too high-toned to give his adhesion to the superficial notion that the body is the seat and source of sin. We need look no further than the catalogue of the works of the flesh' which immediately follows our text, for, although it begins with gross sins of a purely fleshly kind, it passes on to such as hatred, emulations, wrath, and suchlike. Many of these works of the envyings flesh are such as an angel with an evil heart could do, whether he had a body or not. It seems therefore right to say that the one member of the contrast is the divine Spirit of holiness, and the other is man as he is, without the life-giving influence of the Spirit of God. In Paul's thought the idea of the flesh always included the idea of sin, and the desires of the flesh were to him not merely rebellious, sensuous passion, but the sinful desires of godless human nature, however refined, and as some would say, spiritual' these might be. We do not need to inquire more minutely as to the meaning of the Apostle's terms, but may safely take them as, on the one hand, referring to the divine Spirit which imparts life and holiness, and on the other hand, to human nature severed from God, and distracted by evil desires because wrenched away from Him.
The text is Paul's battle-cry, which he opposed to the Judaising disturbers in Galatia. They said Do this and that; labour at a round of observances; live by rule. Paul said, No! That is of no use; you will make nothing of such-an attempt nor will ever conquer evil so. Live by the spirit and you will not need a hard outward law, nor will you be in bondage to the works of the flesh.' That feud in the Galatian churches was the earliest battle which Christianity had to fight between two eternal tendencies of thought--the conception of religion as consisting in outward obedience to a law, and consequently as made up of a series of painful efforts to keep it, and the conception of religion as being first the implanting of a new, divine life, and needing only to be nourished and cared for in order to drive forth evils from the heart, and so to show itself living. The difference goes very far and very deep, and these two views of what religion is have each their adherents to-day. The Apostle throws the whole weight of his authority into the one scale, and emphatically declares this as the one secret of victory, Walk in the Spirit, and ye shall not fulfil the lusts of the flesh.'
