1 Thessalonians 4:15-17
For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent [precede] them which are asleep.
For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:
Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
Rev. 20:5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.
Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice.
And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurection of damnation.
One Rapture, Two resurrections.
2Peter 3:10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
It will come without notice, and no one will be left behind.
