How does Jesus' threat add to what he said in Rev. 3:2?
Revelation 3:3 (ESV)
3Remember, then, what you received and heard. Keep it, and repent.If you will not wake up, I will come like a thief, and you will not know at what hour I will come against you.
Jesus recalls the initial command to “wake up” (be watchful) from Revelation 3:2, and now adds that if these Christians refuse to be watchful he will come like a thief.
3 Remember, then, what you received and heard. Keep it, and repent. If you will not wake up, I will come like a thief, and you will not know at what hour I will come against you.
