1 Thess. 4:15-17,
15 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, shall not precede those who have fallen asleep [those who have died]. 16 For the Lord Himself will 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. 17 Then we who are alive and remain shall be caught up [Greek: harpazo] together with them in the clouds to meet [Greek: apantesis] the Lord in the air; and thus we shall always be with the Lord.
This is an except from Stephen Jones, God's Kingdom Ministries, http://gods-kingdom-ministries.org/COLDFUSION/Chapter.cfm?CID=232 Getting back to Paul's statement in 1 Thess. 4:15-17, he tells us that we will "meet" the Lord in the air. The Greek word used is apantesis, which means "to meet and return with (as an escort)." This Greek word is used four times in the New Testament. It is used in Matt. 25:1 and 6, where the arrival of the Bridegroom was announced and the ten virgins were told to go out "to meet" Him.
The elect who are the chosen of all nations, which are symbolically the 144,000, will resurrect, both living and already dead in the first resurrection. Then, in this excerpt by Stephen Jones.................The truth of the matter, as I see it, is this: Christ is coming to rule His Kingdom, and we will go out to meet Him in some way to escort Him to the earth. The overcomers will then rule with Him as priests (Rev. 20:6). The purpose of the first resurrection is to raise those overcomers from past generations who qualified to rule with Him. Their resurrection will be the first event on the feast-day calendar, th e Feast of Trumpets.
This event will spark a world-wide repentance ("Days of Awe") leading to the Day of Atonement (repentance) on the tenth day from the resurrection. Five days later the living overcomers will come into immortality on the first day of Tabernacles. After seven days of cleansing, according to the law, the Sons of God will then be presented to the Father on the eighth day of Tabernacles.
These 144,000 that will be presented to the Father will then be taken with Jesus to the Mount of Olives as shown in Rev Chap 14. and this will be the time of the harvest. The Angels are the reapers. Just like the Passover, when the angel of death took lives during the plagues in Egypt. So, then, one will be taken and one will be left, as in the days of Noah. The one's taken were the ungodly in the flood. The righteous remained.
Luke 17: 26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all.
28 Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;
29 But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed [them] all.
30 Even thus shall it be in the day when the Son of man is revealed.
31 In that day, he which shall be upon the housetop, and his stuff in the house, let him not come down to take it away: and he that is in the field, let him likewise not return back.
32 Remember Lot's wife.
33 Whosoever shall seek to save his life shall lose it; and whosoever shall lose his life shall preserve it.
34 I tell you, in that night there shall be two [men] in one bed; the one shall be taken, and the other shall be left.
35 Two [women] shall be grinding together; the one shall be taken, and the other left.
36 Two [men] shall be in the field; the one shall be taken, and the other left.
