Again, there is no indication of the "time of the end," fleeing, or anything of that nature. Let us go on to Thyatira in verse 25 where we begin to see a bit of a difference in the closing part of the message.
Not the person's end (which it might be interpreted as, and that is a possibility). When we think of it, within the context of what the book of Revelation is all about, it is about the "time of the end." I think that the number one application here is—there might be people who are in the church, having God's Spirit, alive at "the end," the Tribulation, and the Day of the Lord—people who are part of these people that God classifies as Thyatira.
