There are several different English versions of the text. I took liberties with all of them. I wasn't such a fan of the battle imagery in one verse. (That imagery is fine in a different kind of song, but I don't think it really fits with this melody.) I also modified the verse about being God's son. I wrote this for high voice (mine), and I'm not a son.
My arrangement for high voice and piano is now available under the Music tab.
