Quotes having to do with God

"Omnipotence doesn’t mean that God can do anything. The concept of omnipotence has to do with power, not ability per se. In fact, there are many things God can’t do. He can’t make square circles. He can’t create a morally free creature who couldn’t choose evil. He can’t instantly create a sixty-year-old man (not one that looks sixty, but one that is sixty). None of these, though, have to do with power. Instead, they are logically contradictory, and therefore contrary to God’s rational nature." Gregory Koukl
