Spirit of Freedom, Wake!
As I've been working through this abolitionist hymnal, there are competing themes of struggle against the monsters both within and without regarding the issue of slavery. This song hits a bit more on the internal side - asking for the Spirit of Freedom to rise up and fight off the sins in our own lives that lead to enslavement of others. Let me know what you think about the tune, especially on the "group sing-ability" front.
