If God is all powerful, can He make something He cannot lift?  Being that God is all powerful He can lift anything, yet if He is all knowledge He can make something He cannot lift. The answer to this paradox is found here. 

Bob Hall hates his name, say it out loud, and you'll understand why, sounds really stupid. He's changing his name to Wentworth Wellington Hall, this will instill awe and respect in others. So, from now on he's referring to himself as Wentworth. He'll buy a monocle next week on Tuesday at exactly 3:17pm. Due to the critical time importance he'll be wearing his double-breasted blue color blazer with yellow long johns and purple penny loafers. He knows this will cause the ladies to faint and strong men will whimper like beaten turtles. Wentworth was starting to feel unusually strange in his heart, mind, spirit, and soul because the extremely powerful psychedelics were kicking in. He wasn't quite certain if taking 50 hits of Grateful Dead LSD, a huge ball of Magic Psilocybin Mushrooms and Very Pure DMT at the same time was the grandest idea he'd ever had. He'll find out sooner rather than later.
