Why is the harvest important in Christian eschatology?

In Revelation, the harvest represents the culmination of God's salvific plan where believers are gathered to Him, while the wicked face judgment. Jesus often spoke of the harvest as the time of recompense, where the wheat is separated from the tares (Matthew 13:30). This harvest is critical as it indicates that every human life and action is held accountable before God. It reassures believers of God's sovereignty and justice, and underscores the urgency of the Gospel as the harvest is described as ripe, calling for immediate action.
