I'm an atheist for all practical purposes and there are gospel/religious songs that I like. Sometimes it's a bit of a conflict because I like the music but not the words ("Farther Along") but there are some with very nice images in the words, even if you're not religious.

I always liked, in particular, "It Soon Be Done" (I'm gonna shake hands with all of the elders/tell all the people 'good morning'/sit down beside my Jesus/sit down and rest a while) and "Leaning on the Everlasting Arms". My father appropriated "Turn Your Radio On" for his First Day School class since Quakers do that direct-communication-with-God thing. The kids thought it was hilarious (they're teenagers--they're old enough to understand that it doesn't mean the same thing in our context but they still thought it was a lot of fun).

My mother likes "Precious Memories", I like "Wayfaring Stranger" and "Wondrous Love", and we all like "I'll Fly Away" and "Uncloudy Day".
