On Sunday (8/17/25) at Redeemer, I am preaching on this.
I will not be spending much time on the meaning of the Millennium. Reasons for that choice will be obvious to anyone who has preached or taught on this subject, found only in six verses at the beginning of Revelation 20.
Here are some resources if you want to dig in.
Thomas Schreiner [Fuller Seminary]. "What Is the Millennium?"
N. T. Wright's excursus in Revelation for Everyone, pp. 128 ff.
Craig Keener's excursus in his commentary on Revelation, esp. pp. 470 ff.
See Keener's excursus on "The Millennium" in his Cultural Backgrounds Study Bible, pp. 11819 ff.
