Well...

Here is a set:

I I I I

The set contains exactly: I I I I members.

Can God make a set with exactly I I I I members contain exactly I I I I I members even though it contains exactly I I I I members? If he adds I to the set then it doesn't contain exactly I I I I members anymore. If he doesn't add I to the set then it doesn't contain exactly I I I I I members.

So...

Can God make a set with exactly I I I I members contain exactly I I I I I members?

It isn't about whether he would WANT to or whether he could be BOTHERED worrying about it, it is about whether it is POSSIBLE for him to do so.

I don't see why on earth we should expect him to be able to do this. I don't see why on earth we should see it as a limit on his power that he can't do this. It is an artifact of language.

Same with this:

CAN god make a rock so big that he can't move it?

There are two possible answers (and only two)

1) Yes he can.

But if he can make the rock then he isn't able to do everything because he can't move the rock.

2) No he can't.

But if he can't make the rock then he isn't able to do everything because he can't make the rock.

So either way: God can't do EVERYTHING.

But the problem is an artifact of language: We can define the impossible and thereby describe things that God can't do...
