It was not unusual during such a personal conversation with God for someone to erupt in an emotional outburst of joy. It seems to me that it was easier to concentrate on the words and music because there wasn't anything else demanding one's attention. Today the emphasis has shifted no doubt, even if the purpose has remained somewhat the same. My problem with all this is, take away all the technology, and talented people, and today's congregation believes that worship cannot happen. It may be ever so subtle but the emphasis has shifted.
Form is more important then substance.
It's an old problem in a new robe. I have often felt the same about the praise bands, song leaders, and the like. Are the leaders doing it to entertain or are they leading to glorify God. I dare question some. I see churches incorporating contemporary worship just to bring in people.
