Romans 9:20-22 (NIV)
20 But who are you, O man, to talk back to God? “Shall what is formed say to him who formed it, ‘Why did you make me like this?’” 21 Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use? 22 What if God, choosing to show his wrath and make his power known, bore with great patience the objects of his wrath—prepared for destruction?
"Truly, truly, I say to you, one of you will betray me" (John 13:21). When the disciples asked Jesus to identify the traitor, he replied, "It is he to whom I shall give this morsel when I have dipped it." Then Jesus dipped the morsel, gave it to Judas and said, "What you are going to do, do quickly" (John 13:26-27).
Later that evening in his great prayer of intercession, Jesus said, "While I was with them, I kept them in thy name, which thou hast given me; I have guarded them, and none of them is lost but the son of perdition, that the scripture might be fulfilled" (John 17:12). Here Jesus prayed about Judas, but not for Judas, and called him the "son of perdition."
In Prov. 16:9 we read, "The mind of man plans his way, but the Lord directs his steps." Passages such as this may teach that man has a measure of self-determination, while at the same time indicating that what man freely chooses is also (on some level) directed by God.
The question of man's free will is made more complicated by the fact that we must examine it in man, in terms of how the will functioned before and after the fall of Adam. Most important for us today is how the Fall affected man's moral choices.
1. posse pecarre-referring to the ability to sin.
2. posse non-pecarre-referring to the ability not to sin, or to remain free from sin.
3. non-posse pecarre-referring to the inability to sin.
4. non-posse, non-pecarre-referring to the inability not to sin.
Adam had possessed both the ability to sin (posse pecarre) and the ability not to sin (posse non-pecarre). Adam lacked the exalted state of the inability to sin that God enjoys (non-posse pecarre). God's inability to sin is based not on an inner powerlessness of God to do what he wants, but rather on the fact that God has no inner desire to sin. Since the desire for sin is utterly absent from God, there is no reason for God to choose sin. During his time of "probation" in the garden, he had the ability to sin and the ability not to sin. He chose to exercise the ability to sin and thus plunged the race into ruin.
As a result, Adam's first sin was passed on to all his descendants. Original sin refers not to the first sin but to God's punishment of that first transgression. Because of the first sin human nature fell into a morally corrupt state, itself partially a judgment of God. When we speak of original sin, we refer to the fallen human condition which reflects the judgment of God upon the race. No longer does man have the posse non-pecarre. In his fallen state the plight of man is found in his inability to keep from sinning (non-posse, non-pecarre). In the Fall, something profoundly vital to moral freedom was lost. Augustine declared that in his prefallen state man enjoyed both a free will (liberium arbitrium) and moral liberty (libertas). Since the Fall, man has continued to have a free will, but has lost the moral liberty he once enjoyed.
With respect to the making of choices, fallen man still has the natural ability and the natural faculties necessary to make moral choices. Man can still think, feel, desire. All of the equipment necessary for the making of choices remains. What fallen man lacks is the moral disposition, the desire, or the inclination of righteousness. He is naturally free, but morally enslaved to his own corrupt and wicked desires. Man is still free to choose; but if left to himself, man will never choose righteousness, precisely because he does not desire it.
Man still has not only the ability, but also the built-in necessity, to choose according to his desires. Not only can we choose what we want, but we must choose what we want. It is at this point that the protest is sounded: Is free choice an illusion? If we must choose what we choose, how can such a choice be called free? If we are free to choose what we want but want only what is evil, how can we still speak of free will? This is precisely why Augustine distinguished between free will and liberty, saying that fallen man still has free will but has lost his liberty. It is why Edwards said that we still have natural freedom but have lost moral freedom.
Why talk of freedom at all, if we can choose only sin? The crux of the matter lies in the relationship between choice and desire, or disposition. Edwards's thesis is that we always choose according to the strongest inclination, or disposition, of the moment. Again, not only can we choose according to our strongest desires, but we must choose according to our strongest desires of the moment. Such is the essence of freedom-that I am able to choose what I want when I want it.
If I must do something, then in a sense my actions are determined. If my actions are determined, then how can I be free? The classic answer to this difficult question is that the determination of my choices comes from within myself. The essence of freedom is self-determination. It is when my choices are forced upon me by external coercion that my freedom is lost. To be able to choose what I want by virtue of self-determination does not destroy free will but establishes it.
To choose according to the strongest desire, or inclination, of the moment means simply that there is a reason for the choices I make. At one point Edwards defined the will as "the mind choosing." The actual choice is an effect, or result, which requires an antecedent cause. The cause is located in the disposition, or desire. If all effects have causes, then all choices likewise have causes. If the cause is apart from me, then I am a victim of coercion. If the cause is from within me, then my choices are self-determined or free.
But we are creatures of changing moods and fleeting desires who have not yet achieved a constancy of will based upon a consistency of godly desires. As long as conflict of desire exists and an appetite for sin remains in the heart, then man is not totally free in the moral sense of which Edwards spoke, nor does man experience the fullness of liberty described by Augustine.
