This document discusses several sins related to envy, jealousy, and competitiveness. It defines envy as resenting another's advantage and jealousy as intolerance of rivalry. While some competition can be healthy, it argues true competitiveness seeks to win at others' expense rather than doing one's best for God's glory. The document also discusses controlling behavior in relationships which springs from selfishness rather than humility. Overall it provides biblical perspectives on dealing with these sins by focusing on God's sovereignty rather than comparing ourselves to others.
