The question is why would it be rational to expect creatures to take a servile and supplicatory stance toward their creator
Because He is worthy of it.
especially when the form of the creator's dictates can be proven speculative?
This is question begging, and He has shown otherwise.
He has proven that He is good.
If humans create a humanoid being, would we necessarily expect the humanoids to follow the dictates of the humans without question?
Such a thing isn't possible, but to answer the question for the sake of the argument, yes, we would, because we would be superior to it, just as God is superior to us.
If the humanoids did obey every whim of the humans, would you consider that a good thing? A goal accomplished?
If the goal of creating the humanoid was to have it obey every whim of humans, yes.
Would we expect constant praise?
The problem with these questions is that it assumes that we are the highest authority, and/or that our purpose as humans (in terms of our relationship with God) is to "follow His dictates without question," which I thought I made clear, or at least alluded to, was not the case.
To reiterate: The reason for man's existence is to have a relationship with his Creator, a relationship based on love, not law.
My view is that such a power-over relationship would be a very bad thing. A cautious accumulation of knowledge and insight from experience is far preferable than blind acceptance of conditions with incomplete rationales.
"Blind acceptance of conditions with incomplete rationales"?
Christianity is based on evidence, logic, and reason. God Himself says "Come, let us reason together." Faith is evidence of things hoped for, the substance of things not seen.
Again, you don't get the irony here?
Reminder: YOU said, "It is moral to strive for conditions where each human being has an ample chance to live a full lifespan without undue misery and hardship."
I'm simply pointing out the flaw in that reasoning.
It's quite rational.
If God doesn't exist, and the reason for man's existence is to have a relationship with God, then there's no way to have a relationship with Him, is there?
Quite sad to realize you view the human mind so weak.
I consider trying to comprehend the irrational foolish.
God is not irrational.
In contrast to many Christians, why do conservative Christians come off as incapable of empathy, sadistic, and nearly psychopathic?
I think it's a matter of your paradigm being wrong that causes you to think that we are, when in reality, we're not.
I despise people who pretend to be humble but enjoy their narcissism via a thin veneer of piety.
That's nice.
