On Waiting and Watching
The last Christians will be waiting and watching. They will be ready. And they alone among all humanity will perceive the Lord not as a thief, but as the awaited Savior! "Therefore if you will not watch, I will come upon you as a thief, and you will not know what hour I will come upon you" (Revelation 3:3).
