In the letters to the seven churches in Revelation 2-3, Jesus often warns the churches to repent lest he come and judge them.
For example, in Revelation 2:5, Jesus tells John to write to the angel of Ephesus:
Consider how far you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place.
Or in the letter to Pergamum in 2:16:
Repent therefore! Otherwise, I will soon come to you and will fight against them with the sword of my mouth.
There are similar phrases in the other letters also - in 2:25, 3:3, 3:9, and possibly 3:20.
Should these all be understood as a single "coming" event at which they will be judged accordingly, or as individual threats of Jesus' coming?
