To what might "what remains" refer?

Revelation 3:2 (ESV)

2 Wake up, and strengthen what remains and is about to die, for I have not found your works complete in the sight of my God.

What remains can be a reference to weak members (Ezekiel 34:4, Ezekiel 34:16), but can also be a reference to good (but weak) elements in the congregation other than persons (the Greek term is ambiguous on the point).
