John of Damascus — on Dan 12:2 (BARLAAM AND JOSEPH 19:164-65)

“The dead shall rise again, and they that are in the graves shall awake. They that have kept the commandments of Christ and have departed this life in the true faith shall inherit eternal life; and they that have died in their sins and have turned aside from the right faith shall go away into eternal punishment. Do not believe that there is any true being or kingdom of evil or suppose that it is without beginning, or self-originated or born of God—forget such an absurdity! But believe rather that it is the work of us and the devil, come on us through our inattentiveness, because we were endowed with free will, and we made our choice, of deliberate purpose, whether it be good or evil.”
