Jesus insisted throughout his life-work upon the principle that material factors must be subjected to spiritual values. In order to make this principle clear he often took particular pains to treat material goods with the utmost insignificance. He perceived that individuals are made slaves by the worship of wealth, either on the part of themselves, of the privileged classes, or of society itself. He inaugurated a program of spiritualization which would free the world from the slavery which may come from economic forces. Although a religious teacher above all things else, Jesus insisted upon the necessity of the existence of something more than saving faith alone. He required a social attitude of mind, a heart of social love, and a spirit of service. Give freely to others. Serve others. By giving himself for others, the individual will function in the Kingdom of perfect love, and win other individuals to that Kingdom. Jesus required that love be substituted for hate. Unkind deeds must be supplanted by kind deeds. According to this principle, employers and employees must learn to love one another; and business must be put upon the basis of love and service. Government must be a series of mutual services. Religion must harbor no selfishness. In all human relationships, Jesus reiterated the principle: Love, love, love. This is the spiritualizing and socializing principle by which Jesus proposed to make over the social process. Paul, the apostle to the Gentiles, by virtue of unique experiences and many travels, possessed a cosmopolitan attitude of mind. He gave a practical application of the teaching of Jesus concerning the brotherhood of man. He urged the equal treatment of Jews and Gentiles, bond and free.[VIII-32] He preached the essential unity of mankind. God is no respecter of persons; his Kingdom is a spiritual democracy. We are all--Jew and Gentile--children of the same Father, who gave his son in service for all.[VIII-33] To the call to come over into Macedonia for the purpose of rendering aid, Paul responded immediately and favorably. By so doing he believed that he was carrying out the true implications of the love of God. The greatest tribute that has ever been paid to love as a social force was given by Paul.[VIII-34] Although possessing the highest educational qualifications and being able to speak with the greatest eloquence, any individual leads a practically useless life unless that life is motivated by love. Giving one’s possessions to the poor and sacrificing one’s body counts little if one does these things in any other spirit than that of love. Love protects the individual from envying his neighbors, from becoming proud and haughty and boastful. Love is the greatest principle of life.
