There is a balance to be had between preparation and flowing with the Holy Spirit. The more we prepare, the more we know our music and know the direction to lead our team, the more we can flow with the Holy Spirit during the service. Kent Henry, a song writer and worship leader, uses the phrase "planned spontaneity." The PLANNED part is the excellence, order, not winging it, preparation. The SPONTANEITY part is the moving of the Holy Spirit and God doing what He wants with the service. We PLAN for God to do something SPONTANEOUS by preparing with excellence beforehand!
