Thematic Bible: When sudden destruction shall come

Now brothers, you do not need to have anything written to you about the times and dates [i.e., of Christ's second coming], for you know perfectly well that the day of the Lord [i.e., when He returns, See II Thess. 2:1-2] will arrive like a thief coming in the night. [For] when people are saying, "Peace," and "Safety," then [is when] destruction will come upon them suddenly, like labor pains on a pregnant woman, and they will not be able to escape it.
