There are constant references in 1 and 2 Thessalonians to the return of Christ- history's most amazing event. But what makes the event amazing- as always- is that Jesus is at the center of it. He is our hope in this life and the next!
The apostolic church thought more about the Second Coming of Jesus Christ than about death and heaven. The early Christians were looking, not for a cleft in the ground called a grave but for a cleavage in the sky called Glory. – Alexander Maclaren
