Why does he sing?

Singing has a very definite place in worshipping God in spirit and in truth. We glorify God in our singing praises to His name. There are only nine scriptures in the New Testament which specify the kind of music in the worship of the church that God wishes in order for us to worship Him in spirit and in truth. They are as follows: (1) Matthew 26:30, "And when they had sung a hymn, they went out to the Mount of Olives" ; (2) Acts 16:25, "But at midnight, Paul and Silas were praying and singing hymns to God" ; (3) Romans 15:9, "For this reason I will confess you among the Gentiles, and sing to your name" ; (4) 1 Corinthians 14:15, "I will sing with the spirit, and I will also sing with the understanding" ; (5) Ephesians 5:19, "Speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord" ; (6) Colossians 3:16, "Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord" ; (7) Hebrews 2:12, "In the midst of the assembly I will sing praise to You" ; (8) Hebrews 13:15, "Therefore by Him let us continually offer the sacrifice of praise to God, that is the fruit of our lips, giving thanks to His name" ; (9) James 5:13, "Is any among you suffering? Let him pray. Is any cheerful? Let him sing psalms." All without exception specify only singing. Mechanical instruments of music in the worship of the church are not mentioned in the above scriptures or anywhere else in the New Testament because God has not authorized them.
