The flesh, too, furnished its contingent to the army of our foes. Not that any of our natural appetites, being divinely bestowed, can have in them the nature of sin. No! the flesh, as God made it, is pure and holy. But those instincts, which, regulated by the revealed will of their Author, are "holiness to the Lord," may, by unhallowed gratification, become those "fleshly lusts which war against the soul." As we carry about with us these animal propensities, there is necessity for constant vigilence lest our own nature, being abused, should become our destroyer. Inbred depravity lurks in the heart of even the true believer. Tho dethroned, it is not completely expelled. With what selfishness, covetousness, vanity, hastiness of temper, uncharitableness, have we not to contend! Who has not some sin which most easily besets him? How varied are the forms of unbelief! Spiritual pride, too, corrupts our very graces, piety itself furnishing an occasion of evil, so that when we have conquered some temptation or performed some duty, our victory is often tarnished, our holy things corrupted, by our falling into the snare of self-complacency. Above all, there is that great adversary who "goeth about as a roaring lion, seeking whom he may devour." He avails himself of the world, and the flesh, and the infirmities of the spirit, to tempt the soul of sin. This is no fable, altho one of Satan's most skilful stratagems is to make men disbelieve in his existence. Overlooked or despised, a foe is already half victorious. But the Captain of our Salvation, in His word, often warns us both of the craft and of the violence of our adversary. We sometimes read of "the wiles of the devil"; and sometimes of "the fiery darts of the wicked one." They who fail to watch and pray, are sure to be vanquished by such a foe. These are our enemies! And if we would possess the promise we must "overcome." A mere profession of religion is of no avail. It is not enough for our name to appear on the muster-roll of the camp. Many wear the soldier's dress who know nothing of the soldier's heart. Many are glad to glitter on the grand parade who fall off from the hard-fought, blood-stained battle-field. It is not enough to buckle on our armor; many do this, and lay it aside again. We must devote ourselves to this great daily battle of life. There is no exemption of persons. Women must fight, as well as men; the tender and timid must be as Amazons in the conflict. Children must carry the shield, and wield the sword. The aged and infirm must keep the ranks. The sick and wounded must not be carried to the rear. No substitute can be provided, and there is no discharge in this war.
