The rapture will occur at the 2nd coming
because Christ's coming must destroy the
Antichrist:
2 Thes 2:8
Then shall that Wicked be revealed, whom the
Lord shall consume with the spirit of his mouth,
and shall destroy with the brightness [epiphaneia]
of his coming [parousia].
Titus 2:13b
That blessed hope, and the glorious appearing
[epiphaneia] of the great God and our Saviour
Jesus Christ...
1 Thes 4:15b
The coming [parousia] of the Lord...
Don't lose the blessed hope even if you find yourself
in the great tribulation, for our hope in Christ goes
beyond this life:
1 Cor 15:19
If in this life only we have hope in Christ, we are
of all men most miserable.
2 Cor 4:17-18
For our light affliction, which is but for a moment,
worketh for us a far more exceeding and eternal weight
of glory; While we look not at the things which are
seen, but at the things which are not seen: for the
things which are seen are temporal; but the things which
are not seen are eternal.
Phil 1:23
Having a desire to depart, and to be with Christ;
which is far better...
Phil 1:21
For to me to live is Christ, and to die is gain.
Rom 8:35-37
Who shall separate us from the love of Christ? shall
tribulation, or distress, or persecution, or famine,
or nakedness, or peril, or sword? As it is written,
For thy sake WE ARE KILLED all the day long; we are
accounted as sheep for the slaughter. Nay, in all these
things we are more than conquerors through him that
loved us.
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.
