There's a thread on Barbelith at the moment that I really like and which begins: There's a fairly well known contradiction that derives from seeing God as omnipotent�having unlimited power. It goes kinda� like this:

Could God make a stone so big that even He could not lift it?

If God is omnipotent, then He can lift any stone, but the contradiction, of course, is that His ultimate power ought to be able to create a stone that can�t be lifted�even by Him!

You can find it here.

Barbelith. Don't it rock.
