Pastor Joel addresses the Thessalonian believers' confusion and alarm about end times events, particularly concerning the Day of the Lord and the rapture of the church. He emphasizes the critical importance of sound biblical interpretation using the historical-grammatical method rather than allegorical approaches. He explains that the Thessalonians were troubled by false teaching suggesting they had missed the rapture and were already in the tribulation period. Pastor Joel clarifies the distinction between the rapture (the gathering of believers to Christ) and the second advent (Christ's physical return to earth), presenting a premillennial, pre-tribulation perspective. Central to the sermon is the introduction of the Antichrist (the man of lawlessness) who will be revealed before the Day of the Lord begins. He stresses that proper doctrine directly affects how believers live, warning against being "tossed to and fro" by false teaching. He argues that consistent, literal interpretation of Scripture naturally leads to a pre-tribulation rapture position and that the tribulation events are Israel-centric, not church-centric. Pastor Joel concludes with a call for believers to remember and hold fast to sound biblical teaching.
