When is everybody asleep? At night. That is what "at night" means. Jesus comes back when everybody is asleep, so keep your lamps burning--that is what Jesus keeps saying over and over again. No need to create a false dichotomy where none exists.
You've apparently not read my past posts about:
--"our Rapture" takes place PRECEDING the "IN THE NIGHT" time-period's ARRIVAL [i.e. before the DOTL(-time-period)'s ARRIVAL];
--FOLLOWING "our Rapture" is when the "LAMPS LIT" ("TOOK LAMPS") takes place, and not by US (the "10 Virgins" R NOT US--Jesus is not coming to MARRY "10 [or even 5] VirginS [PLURAl]"--they ain't us, see); I made posts on this [it is this that pertains to the "IN THE NIGHT" time period ("DARK"/"DARKNESS"/etc)];
--the "10 VirginS [PLURAL]" pertain to "the wedding FEAST/SUPPER" (i.e. the earthly MK age, its inauguration), NOT "the MARRIAGE" (pertaining solely to "the BRIDE/WIFE [SINGULAR]" who is not mentioned in the "wedding FEAST/SUPPER" passages [aka the earthly MK age, commencing upon His "RETURN" to the earth]--see again also Luke 12:36-37,38,40,42-44 "when he will RETURN FROM the wedding" THEN the meal! [in this context/contexts, He is RETURNING as an "ALREADY-WED" Bridegroom, FOR "the wedding FEAST/SUPPER"/the earthly MK age)
--much more I could say (that I've put in numerous past posts, on this Subject), but I'm short on time, here... = )
