What biblical book closes with discussions on the final judgment and the fate of unbelievers?

The biblical book that closes with discussions on the final judgment and the fate of unbelievers is Revelation. This book, being the last in the New Testament, provides a detailed prophetic vision of the future, including the end times and the ultimate judgment that will be faced by all humanity. In Revelation, particularly in chapters 20-22, it describes the great white throne judgment, where the dead are judged according to their deeds, and it vividly portrays the final destiny of both believers and unbelievers. The symbolic imagery and the climactic conclusion of God's plan for creation reinforce the themes of justice and hope for believers, while also highlighting the consequences of rejecting God. This makes Revelation the definitive text regarding the final judgment within the context of the entire biblical narrative.

The other options do not focus significantly on the final judgment or the fate of unbelievers. James deals primarily with practical Christian living, Romans covers theological themes including salvation but does not conclude with judgment, and Timothy contains pastoral advice and encouragement without the overarching eschatological context found in Revelation.
