“You are no doubt right in assigning to man a will of some sort, but to credit him with a will that is free in the things of God is too much. For all who hear mention of ‘free-will’ take it to mean, in its proper sense, a will that can and does do, God-ward, all that it pleases, restrained by no law and no command; for you would not call a slave, who acts at the beck of his lord, free.” Martin Luther, Bondage of the Will, 136.
“Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness?” Romans 6:16
