So why do people, decade after decade, keep arguing about the music and life of Amy Grant?

To understand these news stories, it really helps to connect them to other headlines linked to religious believers whose talents allow them to work in mainstream culture. Think about all those debates about the lives of Christian football players, such as Tim Tebow and Russell Wilson. Think about what happens when religious believers, left and right, produce bestselling novels. Think about all those news stories about what is and what is not a "Christian" film. Do the Christians who work at Pixar (and they are part of the mix) make "Christian" movies?

But if you really want to understand this week's Crossroads podcast (click here to tune that in), then I'd like you to take part in a little exercise that I have used for more than a decade in lectures on faith and popular culture.

Step 1: Watch the video at the top of this post, which is Faith Hill's stunning performance of "There Will Come A Day" during the "Tribute to Heroes" special a week after 9/11, a fundraising effort that was carried on just about every single television channel in existence.

Step 2: Now read the lyrics to this song, especially the triumphant final verse and chorus:

There's a better place, Where our Father waits, and every tear, He'll wipe away
The darkness will be gone, the weak shall be strong
Hold on to your faith, there will come a day ...

Song will ring out, down those golden streets
The voices of earth, the angels will sing
Every knee will bow, sin will have no trace
In the glory of His amazing grace ...
There will come a day ... I know there's coming a day

Step 3: Now ask yourself this question: Is this a "Christian" song, in terms of the marketplace of American music? That leads to another question: Is Faith Hill a "Christian" artist, in terms of the marketplace of American music?
