Revelation 1:17-18 (KJV)
17 And when I saw him, I fell at his feet as dead. And he laid his right hand upon me, saying unto me, Fear not; I am the first and the last:
18 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.
What are the keys of hell and death?
I think Jesus said he gave us the keys to the kingdom of heaven. Which is the WORD of GOD. There are 2 keys in the above verse.
