Revelation 1:17-18

17When I saw him, I fell down at his feet like a dead person. Then he put his right hand on me, and he said to me, ‘Do not be afraid! I am the one who is the first and also the last.

18I am the one who always lives. I died once. But look! Now I am alive and I will be alive for ever. I have authority over death and over Hades, the place for dead people.
