Fight the Good Fight

I'm reading Calvin's Institutes in 2009, the 500th anniversay of Calvin's birth. Good reminder today regarding our spiritual enemy:

"We have been forewarned that an enemy relentlessly threatens us, an enemy who is the very embodiment of rash boldness, of military prowess, of crafty wiles, of untiring zeal and haste, of every conceivable weapon and of skill in the science of warfare. We must, then, bend our every effort to this goal: that we should not let ourselves be overwhelmed by carelessness or faintheartedness, but on the contrary, with courage rekindled stand our ground in combat. Since this military service ends only at death, let us urge ourselves to perseverance. Indeed, conscious of our weakness and ignorance, let us especially call upon God's help, relying upon him alone in whatever we attempt, since it is he alone who can supply us with counsel and strength, courage and armor."
