We need to understand that there is a huge difference between art, and spirituality. There is nothing wrong with good art, performance and the rest, but we need to point people to the source of their spirituality and make the definition clear.

What we are seeing now is the ART of worship.. it 'feels' good because the art of worship is very effective in making you feel good.

But, it is not worship. It is art about worship. True worship has nothing to do with music, just as much as love songs have nothing to do with love and loving. I believe that true worship is in our response to being unworthy recipients of grace, which is the only way of receiving grace. We can never deserve grace. Grace is freely given and freely received. Becoming gracious, living in and by grace, extending grace and becoming gracious costs us everything.
Sing! Dance! Clap! Cheer!... but always remember our source of inspiration, our foundation of confidence is in the way that the 'living self portrait' of God, Jesus, bestowed grace on a horribly sin stained world.
