The Element of Surprise
I Thessalonians 5:1-3

  1. But of the times and the seasons, brethren, ye have no need that I write unto you.
  2. For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
  3. For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
