The commandment is, in fact, only the statement of a logical necessity. How could any human being enter into a loving communion with that great Friend whose love is always brooding over our race, who is seeking to do us good and not evil all the days of our lives, who is kind even to the unthankful and the evil,--and not be a lover of his fellow men and a servant of all their needs? It is evident, therefore, that a religion which has no room in it for social questions cannot be the Christian religion. The social question is the one question which Christianity--genuine Christianity--never ceases to ask. The first thing it wishes to know about your religious experience is, how it affects your relations with your fellow men. It insists that your relations must first be right with God, but in the same breath it declares that there is no way of knowing whether or not your relations are right with God except by observing how you behave among your fellow men. Faith is the root, but faith without works is dead, being alone; and works concern your human relations. These principles enable us to determine what is the business of the church. Its business is to foster and propagate Christianity, and Christianity exists to establish in this world the kingdom of heaven. The church is not, therefore, an end in itself; it is an instrument; it is a means employed by God for the promotion, in the world, of the kingdom of heaven. The kingdom of heaven is not an ecclesiastical establishment; it includes the whole of life,--business, politics, art, education, philanthropy, society in the narrow sense, the family: when all these shall be pervaded and controlled by the law of love, then the kingdom of heaven will have fully come. And the business of the church in the world is to bring all these departments of life under Christ's law of love. If it seeks to convert men, it is that they may be filled with the spirit of Christ and may govern their conduct among men by Christ's law. If it gathers them together for instruction or for inspiration, it is that they may be taught Christ's way of life and sent out into the world to live as he lived among their fellow men. Its function is to fill the world with the knowledge of Christ, the love of Christ, the life of Christ. That is what Christ meant by saving the world. The world is saved when this is true of it, and it is never saved till then. The work of the church is successful just to the extent to which it succeeds in Christianizing the social order in the midst of which it stands.
