I think it's obvious that the wording of Revelation 20 concerning the first resurrection is inclusive to the tribulation context. It certainly is not the first resurrection in scripture.
Does "by the word of the Lord" have any significance to you?
For this we say to you
by the word of the Lord,
that we who are alive and remain until the coming of the Lord will by no means precede those who are asleep.
For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God.
And the dead in Christ will rise first.
Then we who are alive
and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord.
Therefore comfort one another with these words.
Our Lord and Savior Jesus Christ says: the error of pre-trib rapture will by NO MEANS OCCUR
for dead in Christ will rise FIRST
AFTER that the rapture of the remaining/alive Saints get "caught up"
How have you no fear of God to add to or take away from His words?
