What does the Bible say about the final harvest?

In Revelation 14, we see the imagery of a great harvest, symbolizing the final gathering of God's people and the execution of judgment upon the wicked. The Lord Jesus Christ is depicted as the one who comes on a white cloud with a sharp sickle to reap the harvest, which consists of the elect gathered into His eternal kingdom, referred to as vessels of mercy. This passage highlights the duality of God's purpose in salvation and judgment, where the righteous are separated from the unrighteous, embodying the ultimate fulfillment of God's sovereignty in history.
