The rock God can't lift.

[Mark 13:13]

You're misunderstanding the point of the question. It isn't can god make a rock he chooses not to lift. The question is can god make a rock he is unable to make, and the relevance is that either answer nullifies god's omnipotence. So, no, he does not remain all powerful.

I suppose if you are saying saying that God can't be omnipotent if that means he can't choose not to do something he has chosen to do.

mmmh maybe i should have read more WIKI as I seem to be reinventing the wheel. lol

Some monotheists reject the view that a deity is or could be omnipotent, or take the view that, by choosing to create creatures with freewill, a deity has chosen to limit divine omnipotence.

Augustine, in his City of God, argued, instead, that God could not do anything that would make God non-omnipotent:
For He is called omnipotent on account of His doing what He wills, not on account of His suffering what He wills not; for if that should befall Him, He would by no means be omnipotent. Wherefore, He cannot do some things for the very reason that He is omnipotent.

Oh well nothing new under the sun it seems.

Why is it christians show a liking for how many angels can stand on the tip of a needle type debates, is it that they are uncomfortable with the real world?

Strangely when I was in school and the history books were using this as a way of suggesting Medieval Scholars were stupid I actually thought the writers of the history books we wrong because I understood that they may have been talking about concepts that were very subtle as the difference between spiritual/physical , power seperated from mass, finite and infinite using the angle needle metaphor so I didn't swallow the Dark ages was just a time of idiots even as per usual the media of the time focused on the same areas as it does now.
