Here is what the Lord through Paul teaches us -
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. 1 Thessalonians 4:15
The resurrection and rapture take place at His coming;
The second coming of Christ.
But now Christ is risen from the dead, and has become the firstfruits of those who have fallen asleep. For since by man came death, by Man also came the resurrection of the dead. For as in Adam all die, even so in Christ all shall be made alive. But each one in his own order: Christ the firstfruits, afterward those who are Christ’s at His coming. 1 Corinthians 15:20-23
