More by Luther on free will...
""free-will" is obviously a term applicable only to Divine Majesty; for only He can do, and does (as the Psalmist sings) "whatever he wills in heaven and earth" [Psalms135:6]. If "free-will" is ascribed to men, it is ascribed with no more propriety than divinity itself would be - and no blasphemy... See More could exceed that! So it befits theologians to refrain from using the term when they want to speak of human ability, and to leave it to be applied to God only."
--Martin Luther
