But as to times and dates, brothers, you do not need to have anyone write to you, for you yourselves know perfectly well that the Day of the Lord is to come like a thief in the night. When people say, "What peace and security!" then suddenly destruction will be upon them, like birth-pains upon a woman about to give birth to a child, and there will be no escape.
