The following paper will provide a sound argument in favor of the existence of God. By demonstrating that an Atheist world cannot account for the preconditions of the laws of logic an Atheist cannot even account for a rational debate concerning the existence of God. "The impossibility of the contrary", the best and only proof that the nesesary truth of the existence of God is his revelation of himself to us that makes it possible for us to use logic. This could be translated, using only nessesary truths, into the form of: L: (laws of logic) G: (God exists) if L entails G L ================ G Logic is "the laws of reasoning that God has established." If God has established these laws of reasoning that we call logic then how could the Atheist system account for the laws of logic. First they are immaterial and universal, and how could anything immaterial and universal be accounted for in a naturalistic (matter only) universe. Second if God has established these laws of reasoning then there would be no atheism. An Atheist wants to believe in laws of logic which are universal in application, but in order to escape the ultimate implications of this idea ( there is a God who imposes universal standards of reason.), the Atheist will try to maintain that the "laws of logic" are merely "conventions" of general agreement amongst them. This is philosophically non-acceptable, if logic were simply a matter of convention, it would be impossible to have any kind of rational debate because either side could win by simply stipulating different laws of logic by convention. Therefore since universal laws cannot be changed by convention since they hold constant in all possible worlds is it not fair to say then that there is a God who imposes universal standards of reason.
