1 Thessalonians 5:2-6 New American Standard Bible (NASB)

2. For you yourselves know full well that the day of the Lord will come just like a thief in the night.

3. While they are saying, "Peace and safety!" then destruction will come upon them suddenly like labor pains upon a woman with child, and they will not escape.

4. But you, brethren, are not in darkness, that the day would overtake you like a thief;

5. for you are all sons of light and sons of day. We are not of night nor of darkness;

6. so then let us not sleep as others do, but let us be alert and sober.
