Much more after Christ came does St. Paul give us this same lesson in the ninth chapter of his first Epistle to the Corinthians: "Every one that striveth for the mastery is temperate in all things," i. e. has power over himself, and keeps himself in subjection, as he presently says. Again, in the seventh chapter, "The time is short; it remaineth that both they that have wives be as though they had none, and they that weep as though they wept not, and they that rejoice as though they rejoiced not, and they that buy as though they possessed not, and they that use this world as not abusing it." Here the same doctrine of moderation or temperance in lawful indulgences is strongly enforced; to weep, to rejoice, to buy, to possess, to marry, to use this world, are not unlawful, yet we must not use God's earthly gifts to the full, but in all things we must be self-denying. Such is Christian self-denial, and it is incumbent upon us for many reasons. The Christian denies himself in things lawful because he is aware of his own weakness and liability to sin; he dares not walk on the edge of a precipice; instead of going to the extreme of what is allowable, he keeps at a distance from evil, that he may be safe. He abstains lest he should not be temperate; he fasts lest he should eat and drink with the drunken. As is evident, many things are in themselves right and unexceptionable which are inexpedient in the case of a weak and sinful creature: his case is like that of a sick person; many kinds of food, good for a man in health, are hurtful when he is ill--wine is poison to a man in a fierce fever. And just so, many acts, thoughts, and feelings, which would have been allowable in Adam before his fall, are prejudicial or dangerous in man fallen. For instance, anger is not sinful in itself. St. Paul implies this, when he says, "Be ye angry and sin not[6]." And our Saviour on one occasion is said to have been angry, and He was sinless. Almighty God, too, is angry with the wicked. Anger, then, is not in itself a sinful feeling; but in man, constituted as he is, it is so highly dangerous to indulge it, that self-denial here is a duty from mere prudence. It is almost impossible for a man to be angry only so far as he ought to be; he will exceed the right limit, his anger will degenerate into pride, sullenness, malice, cruelty, revenge, and hatred. It will inflame his diseased soul, and poison it. Therefore, he must abstain from it, as if it were _in itself_ a sin (though it is not), for it is practically such to him. Again, the love of praise is in itself an innocent passion, and might be indulged, were the world's opinion right and our hearts sound; but, as things are, human applause, if listened to, will soon make us forget how weak and sinful we are; so we must deny ourselves, and accept the praise even of good men, and those we love, cautiously and with reserve.
