While we learn through preaching and teaching, singing in a unique way drives the gospel message into the human heart. The singing of sacred songs helps make spiritual truths a part of our emotional makeup.
As we are “singing and making melody” in our hearts to the Lord, we are at the same time speaking to ourselves “in psalms and hymns and spiritual songs.” (Ephesians 5:19) In congregational singing we teach and admonish one another and thereby allow the word of Christ to dwell in us richly. (Colossians 3:16)
Although instruments of music such as the organ were widely used in the Jewish worship of the Old Testament, in original Christian worship it is the “fruit of the lips” that is an acceptable “sacrifice of praise” to God.
