What does the first resurrection include?
It includes Christ and the first fruits, Church Age believers resurrected at the Rapture, and tribulation saints together with Old Testament believers, pictured as corners and gleanings. This total compilation encompasses all believers of all ages up to the closing days of the tribulation.
Les explains that the first resurrection is pictured as a harvest: Christ and the first fruits were raised at His resurrection; the Church Age believers will be resurrected at the Rapture; and tribulation saints, along with Old Testament believers, are likened to the corners and gleanings left after the main harvest. Once the sampling, main harvest, and gleanings are completed, the field is swept clean, and that total compilation of all believers of all ages up to the closing days of the tribulation is the first resurrection.
