Is this song about a man or God?

There are a couple songs that I hear on country radio (though there may be other genres that do this, too) where, if you interpret the song one way, it's simply a love song, and another way, the song is about the singer's relationship with God. Below are a couple of examples (pay attention to the lyrics, not the videos themselves):

LeAnne Rimes' "I Need You"
Carrie Underwood's "Mama's Song"
Thompson Square's "If I Didn't Have You"

Now maybe I'm reading too much into this, but I think it's interesting to contemplate how songs (poetry in its most popular form) can be understood in multiple ways. And if this actually is what the writer meant, then the song is even more clever than before!
