Now, brothers and sisters, about times and dates we do not need to write to you, for you know very well that the day of the Lord will come like a thief in the night. While people are saying, “Peace and safety,” destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape. But you, brothers and sisters, are not in darkness so that this day should surprise you like a thief. You are all children of the light and children of the day. We do not belong to the night or to the darkness.
1 Thessalonians 5:1-5
