As has happened throughout Biblical history, periods of harmony and cooperativeness have been supplanted with argumentative and quarrelsome changes. In light of today’s society and the recent circumstances in the Church of God, it is important for Christians to understand and to avoid this contentious spirit. This sermon examines the origin of the self-willed approach through Satan. In addition, other examples of the influence of a contentious spirit are given along with the stark consequences of this rebellious attitude.
