Postmillennialists do not deny that there will be tares in God’s kingdom until Jesus returns (Matt. 13:24–30). Still, Dr. Keith A. Mathison notes that “at the end of the age, the Son returns to a field of wheat, not a field of tares” (Postmillennialism: An Eschatology of Hope, pp. 210–211). Whichever millennial view we hold, all believers should have confidence in the Spirit’s power. If we follow His ways and not our own, we can powerfully witness the reign of Jesus.
