Regarding the OP Question, "How do you see these scriptures being fulfilled?"
--
1Timothy 4:1 and Romans 16:17 are speaking of when the Church which is His body (that's us) will still be existing on this earth (that is, in the here and now);
--whereas Matthew 24:
4 / Mark 13:
5 (and contexts) are speaking to the "proleptic 'you'" of
that context (i.e.
those to whom the promised
and prophesied EARTHLY Millennial Kingdom was promised [i.e.
believing Israel--the "proleptic 'you'" basically meaning,
all those in the future OF THE SAME CATEGORY])
... and the
fulfillment of this passage (Mt24:
4 / Mk13:
5 and following) takes place
FOLLOWING "our Rapture," with the Matt24:
4 / Mk13:
5 "G5100 - tis - 'A CERTAIN ONE'" they are to BEWARE of (
in particular, because there will be "
MANY who come in My name, saying..." but
ONE IN PARTICULAR they are to "BEWARE" of especially)
who IS: the "
whose COMING / ADVENT / ARRIVAL / PRESENCE / parousia" of
the man of sin "IN HIS TIME" (i.e. the AC arriving at the
START of the 7-yr Trib [
aka SEAL #1]...
AFTER "the Church which is His body" has been "SNATCHED [G726]" out of here).
... "And
G1161 Jesus
G2424 answering
G611 them G846 began
G756 to say,
G3004 Take heed
G991 lest
G3361 any
G5100 ['A CERTAIN ONE'] man deceive
G4105 you:
G5209 [
"proleptic 'you'" and a "consistent 'you'"]
Hope that makes sense.
