Charles Spurgeon Commentary Revelation 1:17-18

"And when I saw him, I fell at his feet as one dead. And he laid his right hand upon me, saying, Fear not; I am the first and the last, and the Living one; and I was dead, and behold, I am alive for evermore, and I have the keys of death and of Hades." — Revelation 1:17-18 (ASV)

And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last: I am he that liveth, and was dead; and behold, I am alive for evermore, Amen; and have the keys of hell and of death.

This is the great consolation of the people of God when they are brought very low – that Jesus lives, that Jesus reigns, that Jesus still comforts us and draws near to us in all the majesty of his power.
