Thematic Bible: When sudden destruction shall come

Now concerning the times and the seasons, brothers, you have no need [of anything] to be written to you, for [you] yourselves well know that the day of the Lord is coming in the [same] way as a thief in the night. Whenever they say "Peace and security," then sudden destruction will overtake them like the birth pains of {a pregnant woman}, and they will not possibly escape.
