This is an excellent article from World Magazine about how we exhibit (or don't) exhibit our following Christ.
I enjoy Andree Seu's articles since my Mother in Law turned me on to them, and just recently gifted World magazine to my Sister in Law.
In this article, she points out how she doesn't really wear her faith on her sleeve. She likens this tendency to someone who might be exultant of their lover in private but almost secretive about the relationship in public. A good point.
I don't think she is alone in her tendency to keep her faith to herself. Unless your faith is something that is considered "hip" like Kabbalah, the religion of celebrities, or "deep" like Buddhism... then it is more ok to talk about it. There is more Western tolerance (at least on the West Coast) for Islam than if you are a Christ follower. It doesn't surprise me that there is a general "fatigue" about Christians. Christians with the biggest voices also do the faith the most damage often times. And the ones who are without blame are still in the crosshairs of a culture that views Christian tenets as parochial, quaint or hypocritical.
Anyway, it's worth a read.
