"...and the Ever-living One [living in and beyond all time and space]. I died, but see, I am alive forevermore, and I have the keys of [absolute control and victory over] death and of Hades (the realm of the dead)." For all those scared of death. He descended to Hell and took the keys of death and hell. Imagine the God who defeated death and took the keys of hell. The things you fear, fears God.
