The document discusses whether instrumental music in worship is authorized by the Bible. It argues that everything in Christian worship must be authorized by scripture based on various Bible verses. It asserts that the principle of worship is that it must be pleasing to God and authorized by him. The document analyzes several Bible stories and verses demonstrating that God condemned unauthorized worship. It concludes that the Bible only authorizes singing in worship and there is no command or example of playing instruments; therefore instrumental music in churches goes beyond what is biblically authorized.
