In what order does the resurrection of the dead take place according to 1 Corinthians 15:23?

According to 1 Corinthians 15:23, every person is resurrected in his own order or company. Christ is the firstfruits; afterward, at His coming, those who belong to Christ are raised—the believers of all ages, including the Church, Old Testament saints, and Tribulation saints, as the major harvest of God's reaping.

Les explains that verse 23 gives the resurrection order: every man is resurrected in his own order or company. Christ the firstfruits comes first. Afterward, at His coming, they that are Christ's are raised. Les identifies this as all the believers of all the ages from Adam and Eve on up to the end of the Tribulation. This includes the resurrection of the Church, the rapture, the great resurrection day of the major harvest of God's reaping, and then the bringing together of the Old Testament Saints and the Tribulation Saints, as seen in Daniel chapter 12. Verse 24 then introduces the end, when the kingdom is delivered up to God the Father.

1 Corinthians 15:23

But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.

Why does Paul use the word order for the resurrection in 1 Corinthians 15:23?

Paul uses 'order' to show resurrection occurs by organized companies, not all at once. God is a God of order, so He arranges each group—Christ the firstfruits, then each in their own company—to keep track of everyone, much like military organization.
