Luke 21:36
Watch ye therefore, and pray always, that ye
may be accounted worthy to escape all these
things that shall come to pass, and to stand
before the Son of man.

Lk 21:36 doesn't require a pre-trib rapture
because we can escape the tribulation and be
brought into heaven through an early death:

Isa 57:1
The righteous PERISHETH... the righteous is
taken away from the evil to come.

2 Cor 5:8
We are confident, I say, and willing rather
to be absent from the body, and to be present
with the Lord.

Phil 1:23
Having a desire to depart, and to be with
Christ; which is far better...

Isaish 57:1-2
The righteous PERISHETH, and no man layeth it to heart:
and merciful men are taken away, none considering that
the righteous is taken away from the evil to come.
He shall enter into peace: they shall REST in their beds,
each one walking in his uprightness.

Here resting in beds refers to their dead bodies,
while walking in uprightness refers to their spirits:

2 Cor 5:8
We are confident, I say, and willing rather
to be absent from the body, and to be present
with the Lord.

1 Thes 4:14
Them also which SLEEP in Jesus...

We find a NT verse parallel to Isaiah 57:1-2:

Rev 14:13
Blessed are the dead which DIE in the Lord from
henceforth: Yea, saith the Spirit, that they may
REST from their labours...

This refers to Christians whose death will deliver
them from the tortures of the Antichrist.

We must be faithful unto death, whether before or
during the coming tribulation:

Luke 9:24
For whosoever will save his life shall lose it: but
whosoever will lose his life for my sake, the same
shall save it.

Rev 2:10
Fear none of those things which thou shalt suffer:
behold, the devil shall cast some of you into prison,
that ye may be tried; and ye shall have tribulation
ten days: be thou faithful unto DEATH, and I will
give thee a crown of life.
