Who is included in the resurrection of the just at the end of the days?
Included are the Old Testament saints, such as Daniel and his fellow believers, along with the tribulation believers—both Jews and many Gentiles—who believe and are martyred after the church is raptured. These are not members of the body of Christ; they are grouped with the Old Testament believers in the resurrection of the just.
Les explains that Daniel and the Old Testament believers will stand in their lot at the end of the days, which he identifies as the extra 75 days beyond the tribulation. After the church is raptured, the seven years of tribulation bring multitudes of people who believe and are martyred, both Jews and many Gentiles. These are not members of the body of Christ, so Les places them back with the Old Testament believer. Because the tribulation is primarily a Jewish period of God dealing with Israel, with the temple operating, he puts the whole lot of tribulation believers and Old Testament believers into this particular time of resurrection of this group of just people.
