The music is so tight and you guys are super creative. I don't think you need to borrow from secular music and infuse it in a praise and worship session. God has gifted you guys to create new stuff. Secular (which means not of God) waters all that down.
Well when unsaved people sing gospel music this is what happens. Their mannerisms etc are of the world. This is that crowd Jesus was talking about in Matt. He will tell them I never knew you and they will be absolutely surprised.
