1 Thessalonians 5:4 WEB

²  For you yourselves know well that the day of the Lord comes like a thief in the night.

³  For when they are saying, 'Peace and safety,' then sudden destruction will come on them, like birth pains on a pregnant woman; and they will in no way escape.

⁴  But you, brothers, aren't in darkness, that the day should overtake you like a thief.

⁵  You are all children of light, and children of the day. We don't belong to the night, nor to darkness,

⁶  so then let's not sleep, as the rest do, but let's watch and be sober.
