"By Reduction to the Absurd : Suppose that God is in fact all-powerful . If he is all-powerful , then he can do anything . Yet this raises the question , `` If God can do anything , can he make a rock so hard that he himself can not break it ? `` If the answer is yes , then God can not break this rock , so there is something he can not do . If the answer is no , then he can not make such a rock , and thus there is also something he can not do . Therefore , it is impossible that God can do everything , and it is thus impossible for him to be all powerful . I ca n't claim originality for this proof , but I have never heard any good refutation of it , and yet people still act as if God is all powerful despite the absurdity of such a notion . If there is a refutation , then I 'd like to hear it ."
"The question is illogical . By declaring the existence of an all powerful God then saying God can not do something is not a comment on his powerfulness but rather the direct representation of his nature . Your question by its very statement does not test wether or not God is all powerful but wether or not God is comprehensible . See another thread for that topic . The statement that God is all powerful defines his nature . To state then that he can not do something outside of his nature as proof of the non existence of his nature is circular in logic ."
