Just to make sure my stand is clear: my husband and I are not against hymns, against gospel songs, or against contemporary music.
There is good and bad under all the genres.
But we do head for the door if the behavior of the people is crass during the music, or if we feel it is being used to manipulate, or if we believe it is being used in a way to bring the world into the church instead of the church into the world.
Case in point, 2 songs. While In the Garden is certainly not really contemporary, we've seen it used quite well and seen it used in engendering a sappy sentimentalism (thanks Christianity Today for a good description.) Amazing Grace-My Chains are Gone is a sort of combined mish mosh of parts of Amazing Grace and And Can it Be. We've seen it used very manipulatively, but we've seen it used wonderfully and consider it one of our favorite hymns.
Our main challenge is this: if you find yourself unable to make contact with Jesus unless with your favorite music (any genre) or if you find yourself feeling you make better contact with Him with the music than without, consider at least a 30 day detox. Make sure your relationship is with HIM, not emotions stirred up by the music. Then, once you are sure you are in a good place, enjoy.
But do remember that when you are in a public service with your eyes closed, the rest of us can still see everything you wiggle, jiggle, shake, reveal, or touch. We very much want you to "fall in love with Jesus" but it is not a sexual encounter. Behave accordingly.
We are not Puritans and not much into taking their opinions as gospel. We've really put the time into studying what the church service is or should be. We disagree with those that would say it is a performance we do for an audience of One. And we disagree with those that make it an intimate time with Jesus. We do fall in with those that see it as a time for the evangelistic preaching of the Word.
We understand others see things differently.
