Christian Poetry -- Suggestions?

OK, I'd like to pick the collective brains of my LJ friends. I'm seeking suggestions for a present for my Grandmother who, I recently learned, really likes books of poetry. (It never really came up before, the things you learn about the people you love, huh?) She's also 80 years old and probably isn't going to like my favorite poets -- I suspect Shel Silverstein just isn't her cup of sweet iced tea. I know she likes Christian oriented poetry, but ... well, let's just say it's not really a genre with which I'm very familiar nor one I'm likely be become familiar anytime soon.

So ... can anyone make some suggestions based on this criteria? I'm also thinking some 'classic' poets like Frost or Dickinson might be appropriate. Thoughts, anyone?
