Who will be resurrected in the company after the main harvest?
After the main harvest—the Body of Christ saved during the age of grace—and after the tribulation plus an extra 75 days, the Old Testament saints (including Daniel) and the tribulation saints will be resurrected in their own company.
Les explains from I Corinthians 15:23 that resurrection occurs "every man in his own company." He identifies the first company as Christ and the firstfruits. The main harvest, he feels, is the Body of Christ—those saved during this age of grace. Then, after the tribulation has run its course and an extra 75 days pass, the Old Testament saints (including Daniel and all the rest) and the tribulation saints will be resurrected in their company. He also notes that all true prophecy is directed to Israel and that this timeline unfolds God's plan historically.
But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming.
