1 Thessalonians 5:1-5 New Revised Standard Version (NRSV)
5 Now concerning the times and the seasons, brothers and sisters,[a] you do not need to have anything written to you. 2 For you yourselves know very well that the day of the Lord will come like a thief in the night. 3 When they say, “There is peace and security,” then sudden destruction will come upon them, as labor pains come upon a pregnant woman, and there will be no escape! 4 But you, beloved,[b] are not in darkness, for that day to surprise you like a thief; 5 for you are all children of light and children of the day; we are not of the night or of darkness.
