Jesus instructed John to write to the Smyrna Church, using identifiers from the opening appearance of Jesus in Revelation one,
“And to the angel of the church in Smyrna write, ‘These things says the First and the Last, who was dead, and came to life…’” (Revelation 2:8).
Who is Jesus of Nazareth? He is the First and the Last, He is the One who was dead, but came to life, never to die again.
He began all things, and He will end all things. He has all power and all authority.
Do you think you better believe whatever He says, and do whatever He commands?
