This lesson reveals that we should live every day ready for Christ’s return, as did the Thessalonians. The Apostle Paul reminds those brethren, and us, that Christ’s return “in the air” is certain and that the Church will be delivered from the coming wrath. Paul teaches that our greatest joy at the Rapture will be seeing fellow believers gathered together in the Lord’s presence, and also comforts the Thessalonians about believing loved ones who have died—explaining that their souls are already with Christ and will return with Him—meaning we can grieve those losses with hope and not despair.
