Does not then that figure stand forth a living illustration of the _transforming_ power of Christianity? Slaves had well-known vices, largely the result of their position--idleness, heartlessness, lying, dishonesty. And this man had had his full share of the sins of his class. Think of him as he left Colossae, slinking from his master, with stolen property in his bosom, madness and mutiny in his heart, an ignorant heathen, with vices and sensualities holding carnival in his soul. Think of him as he came back, Paul's trusted representative, with desires after holiness in his deepest nature, the light of the knowledge of a loving and pure God in his soul, a great hope before him, ready for all service and even to put on again the abhorred yoke! What had happened? Nothing but this--the message had come to him, "Onesimus! fugitive, rebel, thief as thou art, Jesus Christ has died for thee, and lives to cleanse and bless thee. Believest thou this?" And he believed, and leant his whole sinful self on that Saviour, and the corruption faded away from his heart, and out of the thief was made a trustworthy man, and out of the slave a beloved brother. The cross had touched his heart and will. That was all. It had changed his whole being. He is a living illustration of Paul's teaching in this very letter. He is dead with Christ to his old self; he lives with Christ a new life.
The gospel can do that. It can and does do so to-day and to us, if we will. Nothing else can; nothing else ever has done it; nothing else ever will. Culture may do much; social reformation may do much; but the radical transformation of the nature is only effected by the "love of God shed abroad in the heart," and by the new life which we receive through our faith in Christ.
That change can be produced on all sorts and conditions of men. The gospel despairs of none. It knows of no hopelessly irreclaimable classes. It can kindle a soul under the ribs of death. The filthiest rags can be cleaned and made into spotlessly white paper, which may have the name of God written upon it. None are beyond its power; neither the savages in other lands, nor the more hopeless heathens festering and rotting in our back slums, the opprobrium of our civilization and the indictment of our Christianity. Take the gospel that transformed this poor slave, to them, and some hearts will own it, and we shall pick out of the kennel souls blacker than his, and make them like him, brethren, faithful and beloved.
Further, here is a living illustration of the power which the gospel has of binding men into a true brotherhood. We can scarcely picture to ourselves the gulf which separated the master from his slave. "So many slaves, so many enemies," said Seneca. That great crack running through society was a chief weakness and peril of the ancient world. Christianity gathered master and slave into one family, and set them down at one table to commemorate the death of the Saviour who held them all in the embrace of His great love.
All true union among men must be based upon their oneness in Jesus Christ. The brotherhood of man is a consequence of the fatherhood of God, and Christ shows us the Father. If the dreams of men's being knit together in harmony are ever to be more than dreams, the power that makes them facts must flow from the cross. The world must recognise that "One is your master," before it comes to believe as anything more than the merest sentimentality that "all ye are brethren."
Much has to be done before the dawn of that day reddens in the east, "when, man to man, the wide world o'er, shall brothers be," and much in political and social life has to be swept away before society is organized on the basis of Christian fraternity. The vision tarries. But we may remember how certainly, though slowly, the curse of slavery has disappeared, and take courage to believe that all other evils will fade away in like manner, until the cords of love shall bind all hearts in fraternal unity, because they bind each to the cross of the Elder Brother, through whom we are no more slaves but sons, and if sons of God, then brethren of one another.
