Augustine and Calvin and Jesus on the Fallen will
Augustine argued that there are four states, which are derived from the Scripture, that correspond to the four states of man in relation to sin: (a) able to sin, able not to sin (posse peccare, posse non peccare); (b) not able not to sin (non posse non peccare); (c) able not to sin (posse non peccare); and (d) unable to sin (non posse peccare). The first state corresponds to the state of man in innocency, before the Fall; the second the state of the natural man after the Fall; the third the state of the regenerate man; and the fourth the glorified man.
The debate in the church on the the will has always been (b). Calvin and the Roman Catholic Pighius debated about this in bondage and liberation of the will. Calvin said,
"....man has choice and that it is self-determined, so that if he does anything evil, it should be imputed to him and to his own voluntary choosing. We do away with coercion and force, because this contradicts the nature of the will and cannot coexist with it. We deny that choice is free, because through manâ€™s innate wickedness it is of necessity driven to what is evil and cannot seek anything but evil. And from this it is possible to deduce what a great difference there is between necessity and coercion. For we do not say that man is dragged unwillingly into sinning, but that because his will is corrupt he is held captive under the yoke of sin and therefore of necessity will in an evil way. For where there is bondage, there is necessity. But it makes a great difference whether the bondage is voluntary or coerced. We locate the necessity to sin precisely in corruption of the will, from which follows that it is self-determined."
This aligns perfectly with what Jesus said to the Jews who rejected him:
34Jesus answered them, "Truly, truly, I say to you, everyone who commits sin is a slave to sin. 35 The slave does not remain in the house forever; the son remains forever. 36So if the Son sets you free, you will be free indeed. 37I know that you are offspring of Abraham; yet you seek to kill me because my word finds no place in you. 38 I speak of what I have seen with my Father, and you do what you have heard from your father....Whoever is of God hears the words of God. The reason why you do not hear them is that you are not of God." John 8 34-47
Notice that Jesus does not say you are not of God because you do not hear the words of God. Rather he says, you are not of God ... therefore you do not hear them. In John 10:26 Jesus says something similar to them, "but you do not believe because you are not part of my flock." He does not say "you are not part of my flock because you do not beleive." No he says plainly, "You do not believe BECAUSE you are not part of my flock.
