Jesus preaches his own Easter sermon, when in the book of Revelation he says, "I am the Alpha and the Omega, the Beginning and the End, who is and who was and who is to come, the Almighty (Pantocrator). Fear not! I am the First and the Last. I am he that lives, and was dead, and behold, I am alive forevermore. Amen. And I have the keys of Death and Hades." Because it is Jesus Christ, the Almighty Pantocrator, who has the keys of Death and Hades, we can fear not!
