Reference

Luke 12:35

Let your loins be girded about, and your lights burning;
33

Sell that ye have, and give alms; provide yourselves bags which wax not old, a treasure in the heavens that faileth not, where no thief approacheth, neither moth corrupteth.

34

For where your treasure is, there will your heart be also.

35

Let your loins be girded about, and your lights burning;

36

And ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately.

37

Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them.

Counter-Arguments

The strongest case that this verse does not belong in this theme.

Thief in the Night

The verse speaks of being prepared and vigilant, but it does not contain any language about a "thief" or "unexpected timing" for Christ's coming.
