I believe the true role of the minister in worship is perplexing. One that reminds me a lot of the roles of Christians, to give Christ our burdens, but yet take up his yoke and follow him. We find refuge in becoming a slave. What I mean is we must submit our ministry to God, look to him, and allow him to use us.
As ministers, we must get out of the way and let God do his thing through us. Do we always get out of his way? No. We fail often and have to remind ourselves of just who our Audience is (i.e., God). But he's always faithful! He's been drawing the church into his presence for two millennia (not to mention the tabernacle & temple before that). His people have approached him over that time in numerous ways.
But where do we draw the line between the work of the Spirit and our own preparation? We have/are a generation(s) that is tired of facts, figures, doctrine, logic, and appearances. Rightly so, in my opinion, though we ought not to abandon it all. We long for mystery, transcendence, the numinous and the real/experience. We crave encounter with that which is outside ourselves. Personally, I think we don't know what we're really asking when we seek God's guidance in such a way, and would hesitate to ask if we truly knew.
If we go into a worship time, looking to put on a captivating, entertaining experience, he doesn't usually oblige. If we come to him seeking, honoring, praising, and listening to him in an authentic way, I believe we should watch out, because what he delivers is way beyond the expectations of our little minds. Call it exhilarating, holy, exciting, humbling, convicting, captivating, authentic, a WOW experience, quieting, disquieting, centering or whatever else he desires it to be. Entertaining? As long as He is the audience and we worshippers collectively are the performers, sure. There is an aspect to all of this where the focus has to turn to who we are as worshippers, but we have to remember he is the object of our worship.
