Moreover, the message determines the form, and in large measure the message is the medium. Christians believe that the most important event in the history of the human race was the life, death, and resurrection of Jesus Christ, and that the greatest service which can be rendered to the human race is the explication of what God did for our salvation in Jesus and the application of that message to human life in general. Any wisdom the church may have in matters of political, economic, and social concern, or in therapy, is derivative. Many sermons are moral exhortations, which can be heard delivered with greater skill at the Rotary or Kiwanis Club. Many sermons are political and economic judgments on society, which have been presented with greater wisdom and passion at political conventions.
Many sermons offer personal therapies, which can be better provided by well-trained psychiatrists.
This is the great service which the minister and the church can render the world.
