But there is something of more importance than Paul's inborn delicacy and tact to notice here. Onesimus had been a bad specimen of a bad class. Slavery must needs corrupt both the owner and the chattel; and, as a matter of fact, we have classical allusions enough to show that the slaves of Paul's period were deeply tainted with the characteristic vices of their condition. Liars, thieves, idle, treacherous, nourishing a hatred of their masters all the more deadly that it was smothered, but ready to flame out, if opportunity served, in blood-curdling cruelties--they constituted an ever-present danger, and needed an ever-wakeful watchfulness. Onesimus had been known to Philemon only as one of the idlers who were more of a nuisance than a benefit, and cost more than they earned; and he apparently ended his career by theft. And this degraded creature, with scars on his soul deeper and worse than the marks of fetters on his limbs, had somehow found his way to the great jungle of a city, where all foul vermin could crawl and hiss and sting with comparative safety. There he had somehow come across the Apostle, and had received into his heart, filled with ugly desires and lusts, the message of Christ's love, which had swept it clean, and made him over again. The Apostle has had but short experience of his convert, but he is quite sure that he is a Christian; and, that being the case, he is as sure that all the bad black past is buried, and that the new leaf now turned over will be covered with fair writing, not in the least like the blots that were on the former page, and have now been dissolved from off it, by the touch of Christ's blood.
It is a typical instance of the miracles which the gospel wrought as every-day events in its transforming career. Christianity knows nothing of hopeless cases. It professes its ability to take the most crooked stick and bring it straight, to flash a new power into the blackest carbon, which will turn it into a diamond. Every duty will be done better by a man if he have the love and grace of Jesus Christ in his heart. New motives are brought into play, new powers are given, new standards of duty are set up. The small tasks become great, and the unwelcome sweet, and the difficult easy, when done for and through Christ. Old vices are crushed in their deepest source; old habits driven out by the force of a new affection, as the young leaf-buds push the withered foliage from the tree. Christ can make any man over again, and does so re-create every heart that trusts to him. Such miracles of transformation are wrought to-day as truly as of old. Many professing Christians experience little of that quickening and revolutionising energy; many observers see little of it, and some begin to croak, as if the old power had ebbed away. But wherever men give the gospel fair play in their lives, and open their spirits, in truth and not merely in profession, to its influence, it vindicates its undiminished possession of all its former energy; and if ever it seems to fail, it is not that the medicine is ineffectual, but that the sick man has not really taken it. The low tone of much modern Christianity and its dim exhibition of the transforming power of the gospel is easily and sadly accounted for without charging decrepitude on that which was once so mighty, by the patent fact that much modern Christianity is little better than lip acknowledgment, and that much more of it is wofully unfamiliar with the truth which it in some fashion believes, and is sinfully negligent of the spiritual gifts which it professes to treasure. If a Christian man does not show that his religion is changing him into the fair likeness of his Master, and fitting him for all relations of life, the reason is simply that he has so little of it, and that little so mechanical and tepid.
