A.W. Tozer addresses the concept of universal brotherhood, asserting that it remains an unattainable dream when based solely on the ethics of Jesus. He argues that true brotherhood cannot be achieved without acknowledging the pervasive nature of sin, as exemplified by the biblical story of Cain and Abel. Tozer emphasizes that the teachings of Christ alone cannot overcome the deep-seated issues of jealousy, greed, and hatred that plague humanity. He concludes that the hope for individuals lies in the new birth through Christ, while the ultimate hope for humanity rests in the second coming of Christ.
