"...Speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord..." (Eph. 5:19)

A television documentary on foreign countries showed a family that had a rotating wheel in their home, which was used with praying. Supposedly, when the wheel was spun, it sent the worshiper's prayers up to God. In one's worship, there is no difference in praying and singing with an instrument. Both violate the principles of faith (2 Cor. 5:7), make void the word of God (Mark 7:13), and reject Christ's authority (Col. 3:17).
