Jesus Christ is termed "King of Kings" in the Bible, particularly in the Book of Revelation, 17:14 and 19:16. Jesus says in the Book of Matthew, verse 28:18, that all authority on earth has been given to him. In John 18:36 he says that his realm is not of this earth (Hebrew: olam hazeh, "this world, or age", in contrast with the olam haba, "the world to come", in which he will rule), http://en.wikipedia.org/wiki/King_of_Kings
John 14:2-4 In my Father's house are many mansions: if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also. And whither I go ye know, and the way ye know.
"Restoring what you cannot restore, healing the wound you cannot heal, fixing that which you broke and cannot fix is the very purpose of the atonement of Christ. . . . Save for the exception of the very few who defect to perdition, there is no habit, no addiction, no rebellion, no transgression, no apostasy, no crime exempted from the promise of complete forgiveness. That is the promise of the atonement of Christ." "The Brilliant Morning of Forgiveness," by Boyd K. Packer, GC, Oct. 1995
