Human free will is not found in the bible. Human free will is a human verbal contrivance in defense of God against a human accusation.The accusation is that unless human beings choose from undetermined possibilities God cannot justly hold them accountable. What's more, God has men make the accusation. However, when God has men make that accusation, God never claims that human beings are ultimately in control. Quite to the contrary, the only way God answers that accusation when He has men make it is to point out man's lack of jurisdiction to make the accusation.
You could at least claim it's a philosophical or sophist argument, if you're going with an angle that you're actually trying to use some measure of the logic your god supposedly gave you. But you assert, without any significant argumentation beyond theological fluff, that this is just humans defending an idol.
You then undermine the whole argument by inserting your own unfounded bias about God, suggesting that this is a set up to show how great God is, which is pointless and ineffective apologetics, if there ever was an effective kind at all
Is it really so unthinkable, so unfair, so unjust that the potter would make some items for noble use and some for ignoble use from the same lump of clay?
The relationship between the Creator and the creature is less fair, however you define fair, than the relationship between the potter and the clay.
No, it's not fair, but neither is it unjust.
The potter/clay analogy doesn't work so well, since clay doesn't have any will or consciousness, far as we're aware. So the idea of making some items noble and some ignoble is a bit pointless to think about. I can't think of many clay items that are ignoble myself, if any. But if we assume that we're talking about metal and a smith, the point might be better made, I think, even if it still misses the point that metal by its nature is inanimate and only changes when outside forces act on it.
Creator and creature would be quite unjust in creating some damned and some saved from the start, if that's what you're implying. This would only support a claim that your god made me unable to perceive the spiritual, though I wouldn't phrase it quite that way. In which case, your god damned me from the start.
I find the naturalist's admission to the inability to perceive the incorporeal, spiritual and eternal as a refreshing honesty. At the heart of naturalism is random spontaneity, undetermined possibility, chance. Chance is what man calls the void where the knowledge of God was. Such naturalists inspire me to gratitude for being able to perceive more than the corporeal, spatial and temporal.
As a naturalist, I in no way admit I cannot perceive incorporeal, spiritual or eternal, but assert that they are either at present imperceptible to human technology and science or are fictions of the human mind in the latter two cases. In the same way that there are many tales spun by the human imagination, this in no way validates the religious lore because people hold it sacred.
Chance is in no way the primary aspect of a naturalist worldview, since there are demonstrable laws that keep the fabric of time and space from tearing asunder. If the world was chaos, we couldn't conceivably exist for an extended period of time unless there was an outside force acting on the universe, in which case it would only lend credence to theological speculation
You want to have a smug sense of epistemological satisfaction, be my guest, but it hardly suggests you're right, but only that you're so hard headed, no idea even penetrates your skull, let alone makes any leeway into your mind.
