Why all this boasting about free-will and the power of a man, about the natural ...light of reason? What is but blindness and darkness. Can it do anything than fight against the true faith and Gods word. This is why I reject and condemn as nothing but falsehood every doctrine that lauds our free will. For since apart from Christ, death and sin are our master and the devil is our god and prince, there can be neither power nor might neither wit or wisdom, by which we may prepare our selves for righteousness and life or search for them. On the contrary we are bound to be blinded captives of the devil and slaves to sin, to do and to think whatever our master satan wishes and is opposed to God with his commandments. Ah, what a fine freedom that is!
– Martin Luther
