The New Testament and the Future of the Cosmos is an exploration into the cosmic eschatology of the New Testament. It invites the reader to grapple with two interrelated questions along with the author: (1) What did the writers of the New Testament teach about the fate of the cosmos, and (2) can we synthesize their teachings into a coherent New Testament theology? By offering a close reading of key texts that inform the topic (most notably Matt 24:29–31; Mark 13:24–27; Luke 21:25–28; Rom 8:19–22; Heb 12:25–29; 2 Pet 3:4–13; and Rev 21:1–5), it is argued that one can, with certain qualifications, ascertain a clear and coherent New Testament message pertaining to the future of the cosmos. Along the way, new exegetical ground is broken in several passages by identifying a previously unnoticed theme that runs throughout the New Testament concerning the future of the cosmos: God’s judgment of the heavenly powers of evil as a key component to the cosmic transition. At present, these hostile powers hold the cosmos captive to death, but on the Day of the Lord they will be overthrown, setting the stage for a materially transformed world to emerge from the hand of God.
