The brotherly love of the early Church was not only visible to the world; it was its great recommendation in the world's eyes. It had brought a new thing into being, a thing for which the world was pining, namely, vital society. The poor people in the cities of Asia and Europe saw with wonder, joy, and hope, men and women united to one another in a spiritual union, which gave scope to all their gifts for society, and satisfied all their desires for it. The early Christian churches were little companies of people where love was at a high temperature, where outward pressure very often tightened the inward bonds, and where mutual confidence diffused continual joy. Men were drawn to them irresistibly by the desire to share this life of love. It is the very same force which at this moment draws those who are outcasts from society into the Salvation Army. Whatever the failings of that organisation may be, its members are as brothers; the sense of union, of mutual obligation, of mutual confidence, in one word, of brotherly love, is very strong; and souls that pine for that atmosphere are drawn to it with overpowering force. It is not good for man to be alone; it is vain for him to seek the satisfaction of his social instincts in any of the casual, selfish, or sinful associations by which he is often betrayed: even the natural affection of the family, pure and strong as it may be, does not answer to the width of his spiritual nature; his heart cries out for that society founded on brotherly love which only the Church of Christ provides. If there is one thing more than another which explains the Church's failure in missionary work, it is the absence of this spirit of love among her members. If men were compelled to cry still, as in the early days of the gospel, "Behold these Christians, how they love one another," they would not be able to remain outside. Their hearts would kindle at the glow, and all that hindered their incorporation would be burned up.
The Apostle acknowledges the progress of the Thessalonians. They show this brotherly love to all the brethren that are in all Macedonia; but he beseeches them to abound more and more. Nothing is more inconsistent with the gospel than narrowness of mind or heart, however often Christians may belie their profession by such vices. Perhaps of all churches in the world, the church of our own country is as much in need of this admonition as any, and more than most. Would it not be higher praise than some of us deserve, to say that we loved with brotherly cordiality all the Christian churches in Britain, and wished them God speed in their Christian work? And as for churches outside our native land, who knows anything about them? There was a time when all the Protestant churches in Europe were one, and lived on terms of brotherly intimacy; we sent ministers and professors to congregations and colleges in France, Germany, and Holland, and took ministers and professors from the Continent ourselves; the heart of the Church was enlarged towards brethren whom it has now completely forgotten. This change has been to the loss of all concerned; and if we would follow the Apostle's advice, and abound more and more in this supreme grace, we must wake up to take an interest in brethren beyond the British Isles. The Kingdom of Heaven has no boundaries that could be laid down on a map, and the brotherly love of the Christian is wider than all patriotism. But this truth has a special side connected with the situation of the Apostle. Paul wrote these words from Corinth, where he was busily engaged in planting a new church, and they virtually bespeak the interest of the Thessalonians in that enterprise. Christian brotherly love is the love which God Himself implants in the heart; and the love of God has no limitations. It goes out into all the earth, even to the end of the world. It is an ever advancing, ever victorious force; the territory in which it reigns becomes continually wider and wider. If that love abounds in us more and more, we shall follow with live and growing interest the work of Christian missions. Few of us have any idea of the dimensions of that work, and of the nature of its successes. Few of us have any enthusiasm for it. Few of us do anything worth mentioning to help it on. Not very long ago the whole nation was shocked by the disclosures about the Stanley expedition; and the newspapers were filled with the doings of a few profligate ruffians, who, whatever they failed to do, succeeded in covering themselves, and the country they belong to, with infamy. One would fain hope that this exhibition of inhumanity would turn men's thoughts by contrast to those who are doing the work of Christ in Africa. The national execration of fiendish wickedness is nothing unless it passes into deep and strong sympathy with those who are working among the Africans in brotherly love. What is the merit of Stanley or his associates, that their story should excite the interest of those who know nothing of Comber and Hannington and Mackay, and all the other brave men who loved not their lives to the death for Christ's sake and Africa's? Is it not a shame to some of us that we know the horrible story so much better than the gracious one? Let brotherly love abound more and more; let Christian sympathy go out with our brethren and sisters in Christ who go out themselves to dark places; let us keep ourselves instructed in the progress of their work; let us support it with prayer and liberality at home; and our minds and hearts alike will grow in the greatness of our Lord and Saviour.
