Hubby and I saw a Mennonite couple -- on my birthday, over the summer -- on the way to the cinema doing their part for Christ's mission. They were nearly a stereotype: he wore a beard and suspenders; she, a plain dress and a "sin sifter" bonnet, trying to distribute something.
I had to have what they were giving out.
Rather nice: a CD entitled Secure in Jesus, with a little copy of the Gospel of John (without comment or leading directions) added. The singing was a set of pleasant typically-Free Church gospel tunes, with a little spoken sermonette halfway through.
A tad frumpy, but would have been welcome enough if I were already sympathetic to the kind of churchmanship and had a CD assisted commute. But then again, the Mennonite image is hardly hot hot sex sex.
A more stylish (but fully self-integrated, of course) church might try a version of this outreach. Music style goes far to targeting the populations you want to reach, and religious music has more genres than ever before.
