17 "When I saw him, I fell at his feet as though dead. Then he placed his right hand on me and said: “Do not be afraid. I am the First and the Last. 18 I am the Living One; I was dead, and now look, I am alive for ever and ever! And I hold the keys of death and Hades."
One can only imagine the feeling John must have had at this point being confronted with all this overwhelming sound and imagery, but Christ is quick to comfort him and tell him not to be afraid.
