I think the American church would gain a lot of discernment if we would learn to find the line between emotion and worship. Not that the two aren't (or shouldn't be) coexistent, but that there is a very real distinction between the two. There's error on either side; some want no emotion in public worship, some don't think it's a "worship experience" if there's no 'feeling' created.
Some don't know the distinction between corporate worship and the worship which is all of life. Some refer to music alone as worship, when technically the whole service - the invocation, the sacraments, the Word, the psalms, hymns, songs - is all worship.
Some don't think that emotion in worship is dangerous. Some don't think that it's necessary. Both are wrong.
Some pick churches simply based on the effectiveness of the music to stir emotions. Some churches spend much time and money on creating that, so that those people will be drawn.
Just some thoughts. Now I need to go teach. Here, watch a robot play "giant steps".
