New Testament | 1 & 2 Thessalonians

In Dr. Michael McKay’s New Testament lecture on 1 and 2 Thessalonians, he explores Paul’s earliest teaching on Christ’s return—the Rapture, the Day of the Lord, and how these truths give believers lasting hope and motivation for faithful living.

Dr. McKay introduces Paul’s two Thessalonian letters as early, hope-filled writings to a young church facing persecution and confusion about Christ’s return. Written around AD 50 during Paul’s second missionary journey, these letters reveal that the expectation of Jesus’ return was not an advanced theological concept—it was foundational teaching meant to shape everyday faith and endurance.

In 1 Thessalonians 4–5, Paul explains that believers who have died (“fallen asleep”) will be resurrected first when Christ returns, followed by those still living, who will be “caught up” together with them to meet the Lord. This passage forms the basis for the biblical understanding of the Rapture, a moment of comfort and reunion for all believers. In chapter 5, Paul shifts to the “Day of the Lord,” a theme rooted in the Old Testament prophets like Joel—a time of both divine judgment and salvation. Dr. McKay traces how Paul assures the Thessalonians that they are not destined for wrath, urging them to live soberly, faithfully, and expectantly.

In 2 Thessalonians, Paul addresses new misunderstandings that the Day of the Lord had already passed and corrects those who had stopped working in anticipation of Christ’s return. His message remains consistent: hope in the returning King should not lead to idleness but to greater faithfulness.

This lecture emphasizes that eschatology—the study of the end times—is not meant to inspire speculation or fear but to anchor believers in hope. For Paul, the promise of Jesus’ return is both a comfort in suffering and a call to live with purpose, perseverance, and holiness until the day believers are gathered to be forever with the Lord.
