If God can do anything can he make a mistake?

Can we consider the possibility that it isn't for him? Jesus said the greatest commandment is to love God. Seems to me a case could be made that loving God is what makes us not want to sin...

"If you truly love and his will, then doing what you will, will in fact be doing God's will." (Peter Kreeft, I think. Or maybe it was CS Lewis. I don't remember.)
