" I will say something still easier. Take a single flea or louse-since you tempt and mock our God with this talk about curing a lame horse-and if, after combining all the powers and concentrating all the efforts both of your good and all your supporters, you succeed in killing it in the name of free choice, you shall be victorious, your case shall be established, and we too will come at once and worship that god of yours, that wonderful killer of the louse. "

― Martin Luther , The Bondage of the Will
