Which book's theme includes the Second Coming of Christ?

• A. Romans
• B. 1 Thessalonians
• C. Colossians
• D. Philippians

Answer: (B)

The main concept here is the anticipation of Christ’s return—the Second Coming—as a central focus in a New Testament letter. First Thessalonians is where this topic is most clearly taught. Paul writes to comfort and instruct the church about what happens to believers who have died and what will occur when the Lord returns. In the passages about the coming of the Lord, he describes believers being raised or caught up to meet the Lord in the air and emphasizes living in readiness and holiness in light of that event. This explicit emphasis on the return, the resurrection of the dead, and the gathering of believers is what makes this book the best fit for a question about the Second Coming.

Other books touch on related ideas or exhort in ways that are not centered on the Second Coming. Romans focuses more on justification by faith and living by the Spirit, Colossians on the supremacy of Christ and reconciliation, and Philippians on unity, humility, and perseverance. Their treatment of the return is not the primary theme, so First Thessalonians stands out as the book whose core themes revolve around the Second Coming.
