Since God is all-powerful, I don’t see how this could make the bible a fraud or God a liar, or any of those things. They can remain exactly as one believes. I think God made each of us individually, allowing for more than one of what we, men, believe to be truths.
Certainly there is more than one thing that is True, but — by definition — two things that conflict cannot both be True. While it is the case that many apparent conflicts between truth-claims are entirely resolvable upon studious examination, that is not always the case, and when it is not the case, there is only one position that can be True.
So it is in this case: either the bible is True in its portrayal that man does actually have the freedom to make choices that are wholly volitional, and man Truly does have that freedom, or man does not have that freedom, and the bible is not True in its portrayal that he does. The Author is either presenting Truth about reality, or purveying a lie about reality. There is no “both/and” solution, here, nor is there space for the blandish modernism “well, that’s fine for you, but I believe otherwise.”
Man either has free will or he does not. The bible portrays that, with rare exceptions, he does; its Author asserts a position on the question, and that assertion must be either consistent with reality, or contrary to it.
If it is consistent, then The Author is truthful, if it is contrary, then The Author is a liar. The Author cannot simultaneously be both.
The matter cannot be simplified beyond this, although I’m certain it would take little more than a PhD in philosophy to completely obfuscate it.
