“The Day of the Lord will come just like a thief in the night.” (1 Thessalonians 5: 2) We do not know the day or the time, just as we do not know when the thief comes to rob our home. We are able to prepare for the thief, but we can not read his mind; we can not determine the day or the hour he will arrive. So is the Day of the Lord.
“We who are alive at the Lord’s coming will certainly have no advantage over those who have fallen asleep.” (1 Thessalonians 4: 15) Both the dead and those who remain alive will be equally surprised, equally delighted.
For the dead will rise first, and those alive will join with “them in the clouds to meet the Lord in the air and so we will always be with the Lord.”
“Stay awake and be serious.” (1 Thessalonians 5: 7) “For God does not appoint us to wrath, but to obtain salvation through our Lord Jesus Christ, who dies for us, so that whether we are awake or asleep, we live together with Him.” (1 Thessalonians 5: 9 – 10)
