Question for Russian speakers.

[SOXBLOX]

I was listening to, and following along with, a recording of "The March of the Siberian Riflemen". Not sure if it's a widely known song in Russia these days, but I enjoyed it. 

The question is, part of the translation was bad. In the line нашей верою горя, it translated горя as "sorrowly", which is nonsense. As near as I can figure from my dictionary, горя is a form of горячий, and has the figurative meaning "fervent". This seems correct in context, but I don't know for sure. Is this some normal word form, or is it poetic license?
