Did God give us a false understanding of ourselves?

A further argument for freewill is that men think that it exists. Within my mind I am certain that I have freedom of my own choices. I think it likely that others think the same way. Granted some cultures have a more fatalistic view of life, but even if their outlook is, "If God wills it," they still think that they are making some decisions.

That I think I have freedom to make choices comes from God. If in reality I do not have that freedom, that is all my thoughts and actions are essentially God's thru me, then I think this implies that God is deceitful. Of course God can do as he wills, but deceiving all men totally (thru general revelation) about an aspect of reality does not seem to be in God's nature.

One may argue that my fallen nature prevents me fully understanding myself, let alone God. The problem with this argument is that it is not claiming that I do not fully understand my freewill, rather it is claiming that my belief I have freewill is completely incorrect. There are many attributes that we have because of God's image, and these are broken because we are fallen; The more we take on the mind of Christ the more we can rightly understand these attributes; but I can think of none that are so broken that our view is completely the opposite of reality.

Take justice. Even though this can be very distorted such that gross injustices are done, the concept that there is an ought remains. And those doing injustice frequently do so claiming they are doing true justice, the appeal to justice (albeit false) is still there.

Take design. Even an extreme Darwinian, while accepting a false path to the complexity of life, acknowledges that proteins, structures, cells and organisms work. So they would deny design but can still see function.

Take truth. Even liars are usually aware that they speaking unreality. It takes a long legacy of deceit to no longer be able to tell the difference between truth and untruth in one's own life, and even then there is an awareness of some aspects of reality.

The claim that freewill does not even exist but is only a false belief of our mind is not consistent with the other attributes. It is the odd one out. The claim is not that part of the image of God is broken, it is a claim that we think this way despite being completely incorrect. And even worse, freewill is an attribute that God does have, and we falsely think he has given it to us.

And those who are redeemed still have this sense of freedom within them. Even those who subscribe to no-freewill theology still feel they have some freedom of their decisions.

So we have a claim that humans think they have an attribute that God really has, yet they are incorrect in their thoughts (not just broken reasoning), and even redemption is not enough to alter these intrinsic thoughts.
