Hi John and Doves,
1 Thessalonians 5:1 But of the times and the seasons, brethren, ye have no need that I write unto you. 2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
"The day of the Lord" referenced here points to the 7 years tribulation. What Paul says is the tribulation shall come as a thief in the night.
3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
I believe Paul is mentioning the Jews here. When the Jews say peace and safety, which is Shalom in their language, sudden destruction which is rapture shall come upon them, so that they shall not escape.
Question is, what makes the Jews say Shalom to each other? Since I have the rapture on Iyyar 6, a day after their Independence day (Iyyar 5), I believe the Jews are celebrating their Independence Day, saying shalom ( peace and safety)) to each other. They are in festival mood. While they are doing so, all of sudden rapture occurs, which brings in sudden destruction to them, so that none can escape the subsequent tribulation.
This could be my final conclusion re Paul's message in 1 Thessalonians 5:1-3.
