Well, I've always thought that Mark believed in God, even during his Creed days. And I think he now calls himself a Christian, even though he does not believe in organized religion. I remember hearing that somewhere, whether it was here or at ABband.net.
It's entirely possible that this(or other songs on ODR) could be spiritual. You don't have to be a "Christian" band to write spiritual songs. This fact has been illustrated by bands like U2, Creed, Switchfoot and countless others.
Mark DOES directly reference God in one of the songs on ODR. That song is In Loving Memory. "I'm glad He set you free from sorrow." That appears on the lyrics on AB's official site. Obviously, when He is capitalized like that, that is a reference to God. This doesn't make AB a Christian or even Spiritual band, though.
I'd like to close by saying that I love that AB, like Creed, leaves the songs open to interpretation. That makes for some fun debates on sites like these.
