The decision to worship, like any other decision in life, is based upon three things: intellect, emotion, and volition. What I think about it, how I feel about it, and what I do about it. The act of worship stands upon the tripod of these faculties of the individual. The law of worship is in the heart, placed there by God himself. But the choice of what or whom to worship rests with the individual. As we sample specimens of worship in every era, it becomes apparent that God has always accepted audible worship. Not only does He accept this vocal expression from an individual, but prayer and praise in concert is prominent throughout the Scriptures.
