We must understand the power of music if our worship is to connect with the people who need to gospel in our various cultures. Idiom refers to the type of music, Eph. Songs express our hearts. New songs express new spiritual vistas. Spiritual growth calls for variations in our music.
Music loses meaning with overuse.
Without variety, music that was formerly vibrant with meaning can become meaningless repetition. The past is not failure, the past is history. Those who lived before us answered God's call in their world, we must answer God's call in our world. The world moves on, culture moves forward. We cannot seek restoration by imitating forms and functions of former times, even if those we imitate were very successful.
