First of all there is a similarity between Shai'tan and Satan. Next the title of the Mi'hale ( The Dragon's second) and Michiel (One of God' stop angles). There is also the matter of Rand=Jesus. Jesus is the LAMB of God and his flock is mankind, and Rand is a SHEEPherd. Both are the savior of man. The second coming of either marks the Apocalypse (the Dark One is loose). Now, as in the Wheel of Time, in the Book of Revelations, Jesus breaks the 7 SEALS proclaming dooms day. This means that Rand will smash the seals cleaning saidin and freeing the Dark One of his own free will (with the help of LTT) and he will win. As for the matter of Rand's blood staining the rocks of Shayol Ghul, Rand will die the moment of a total eclipse and the world will be broken again. When the sun rises again so shall the Lord of the Morning and everyone will be happy.
