This essay aims to find out if there’s any way to consolidate Martin Luther’s ideas regarding free will set forth in his work On the Bondage of Will with a more modern, libertarian understanding of the free will. This is done to ultimately see if Luther’s teachings on the subject can be harmonized with Alvin Plantingas “free will defence” in regards to the problem of evil or if these two ideas are fully or partly incompatible. I conclude in the end that while Luther’s ideas and the free will defence might seem incompatible at face value, if you look at the purpose behind the free will defence, namely explaining the existence of moral evil in the world despite an omnipotent, omniscient and benevolent creator then Luther’s idea that the will of man is bound to do evil fulfils the same purpose.
