It doesn't even come close to addressing the double negation which is:
If god cannot create a rock that god cannot lift = god can always create a rock that god can always lift = omnipotence
The statemate appears to be communicating a lack of power, but it actually means unlimited power.
Besides that it spends a lot of time insulting people, and asking the question can god tell a lie.
The simple answer, which it admits, is YES! Of course god can tell a lie. The Christian bible, and Christians deny it. But what they mean by this denial, or even if it's an accurate translation, is irrelevant. The contradiction is not with the concept of an absolutely omnipotent-god. The contradiction is either in the Christian bible, or in the Christian's understanding of it.
I posted this yesterday:
Omni-benevolent is also a choice. Not a limitation. The omnipotent could choose to do evil, but it doesn't.
Not telling a lie, is not a limitation on god's omnipotence. it is a choice to be omni-benevolent.
It also speaks briefly about mutual exclusive properties: creating square-circles, married-bachelors, etc.. Those are easily resolved as well. Of course an omnipotent being can create these things. Changing the language, changing the defintions, works. Which is they way is answered this yesterday. But also, these things have *already* been created. They exist as concepts, as contradictions. That's what they are. They HAVE been created.
Anyway, there have been NO logical challenges presented to absolute omnipotence-god-concept. Double-negation and misinterpretation of the so-called contradictions is the root of most these challenges. Proper comprehension of the meaning of these statements renders them into limitations which naturally are not consistent with omnipotence. The concept of god lying, is a limitation Christians are putting on their version of god, but I am not. And they might not be either. And mutually-exclusive proporties aren't a problem either.
Most important:
you are not only trying to redefine omnipotence but logic as well.
No! I'm not. I am describing an absolutely omnipotent god.
If you want to redefine omnipotence to mean power over everything except the ability to limit their own power
No! I'm not redefining anything.
Unlimited power was your definition. That's what I'm using. Absolutely unlimited. If you want to include "creating a rock that can't be lifted" in the definition, that IS redefining omnipotence into an omnipotent+impotent hybrid.
And can god lie? Yes! But god chooses not to.
If you want to debate and discuss, please address my primary argument:
God can't create a rock that God can't lift = omnipotence.
