It was probably by sheer strength of will and by the grace of Christ that Paul subdued his body. Many in all ages have striven to subdue it by fasting, by scourging, by wakefulness; and of these practices we have no right to speak scornfully until we can say that by other means we have reduced the body to its proper position as the servant of the spirit. Can we say that our body is brought into subjection; that it dare not curtail our devotions on the plea of weariness; that it dare not demand a dispensation from duty on the score of some slight bodily disturbance; that it never persuades us to neglect any duty on the score of its unpleasantness to the flesh; that it never prompts us to undue anxiety either about what we shall eat or drink or wherewithal we shall be clothed; that it never quite treads the spirit under foot and defiles it with wicked imaginings? There is a fair and reasonable degree in which a man may and ought to cherish his own flesh, but there is also needful a disregard to many of its claims and a hardhearted obduracy to its complaints. In an age when Spartan simplicity of life is almost unknown, it is very easy to sow to the flesh almost without knowing it until we find ourselves reaping corruption.
Probably nothing more effectually slackens our efforts in the spiritual life than the sense of unreality which haunts us as we deal with God and the unseen. With the boxer in the games it was grim earnest. He did not need any one to tell him that his life depended on his ability to defend himself against his trained antagonist. Every faculty must be on the alert. No dreamer has here a chance. What we need is something of the same sense of reality, that it is a life-and-death contest we are engaged in, and that he that treats sin as a weak or pretended antagonist will shortly be dragged a mangled disgrace out of the arena.
