ANSWER: The difference is that human beings can worship! Instruments cannot! Neither can they satisfy the purpose of God in the music that He has authorized. In Ephesians 5:19 and Colossians 3:16, we learn that God-approved music in worship demands “singing,” “making melody in our hearts,” “speaking,” teaching one another,” and “admonishing one another.” The instrument does not and cannot answer to, or fulfill, the demands of music in Christian worship! Only human beings in compliance with His will can satisfy these scriptural requirements!
