To your reply in Post 15 -- I am the Programing Director in a seeker targeted church in Winchester, VA. We use all different types of media to get the message across. Secular music that is relevant to the lesson, Christian rock, movie clips, drama and videos that we create ourselves. No tradtional hymns used at our church unless the music is updated.
What matters most is that these artists are planting seeds in the unsaved. If you don't think that God is powerful enough to use anything to bring unsaved people salvation, then I respectfully question your faith. I've seen it happen many times in the past 6 years that I have been a leader in Grace Community Church.
