I really don't need to write to you about how and when all this will happen, dear brothers and sisters.
References for 1 Thessalonians 5:1
For you know quite well that the day of the Lord will come unexpectedly, like a thief in the night.
When people are saying, "All is well; everything is peaceful and secure," then disaster will fall upon them as suddenly as a woman's birth pains begin when her child is about to be born. And there will be no escape.
But you aren't in the dark about these things, dear brothers and sisters, and you won't be surprised when the day of the Lord comes like a thief.
For you are all children of the light and of the day; we don't belong to darkness and night.
So be on your guard, not asleep like the others. Stay alert and be sober.
Night is the time for sleep and the time when people get drunk.
But let us who live in the light think clearly, protected by the body armor of faith and love, and wearing as our helmet the confidence of our salvation.
For God decided to save us through our Lord Jesus Christ, not to pour out his anger on us.
