I'll say it anyway. I don't like going to Christian concerts and listening to an overly-long plea to get involved in a cause (like Samaritan's Purse, World Vision, Compassion International, etc.).
I know this makes me sound like a total, insensitive, selfish heel. And I am.
Still, I've been to two concerts by Christian bands recently, and both times there was a REALLY long appeal to contribute money, sponsor a child, or whatnot. This seems to be par for the course at Christian concerts. I'm going back in my mind to all the ones I've been to over the years (DC Talk, Audio Adrenaline, Michael W. Smith, Newsboys, etc.) and it seems there's always a "ministry" time during intermission or at the end. And if memory serves, it's normally way too long and guilt-motivating.
Conversely, I've been to "secular" concerts where there was no such appeal, and the time was entirely given over to the performance of great music, so that we the concert-goers could celebrate the talents of the artist without hearing one of them say, almost apologetically, "You know, it's not really about the music, it's about caring for people."
One of my concerns is that a lot of non-Christians attend Christian concerts and I'll bet they get completely turned off by this. Plus I'm afraid it communicates something we don't really believe.
A Biblical worldview says that you don't have to baptize art with a Christian message for it to be worthwhile. Now hear me out... I'm not suggesting for a moment that these wonderful Christian artists are consciously doing that. They have good hearts and pure motives when they ask us to meet needs around the world. And I sincerely appreciate what they're doing. They could have chosen to be in the music industry for the glory and fame, but they didn't. And I'm proud of them for that.
But I would argue that it would be better to give us more of their art, without suggesting (even unconsciously) that the art has to be servant to a cause of some kind. For if music or art is just a means to an end, it becomes manipulative and superfluous. For the Christian, the arts are ends in themselves, a display of the glory and beauty of God.
Let us enjoy that without feeling guilty for not contributing to a cause.
