God = Garu-Stu

 Well, if a Mary-Sue/Garu-Stu is a ridiculously powerful character that have all the powers, immortality and all...Then God is the biggest Garu-Stu of the planet, since he is the all mighty and powerful, able to do things in the way he sees fit, blessing, healing, giving and taking life and being immortal... Don't you think that sounds a bit too ridiculously powerful? XD

 Come on, people! I'm pretty sure you don't mind a little funny thing like this! XD
