A "Great" Leader's Fall

There's something ominous whenever you read, see, or hear the words, "Beware." You immediately perk up. Before that moment, you may have been half-attentively walking on a trail. Now you're on full alert, especially if the sign says—I don't know—Beware, bare den nearby. Gulp. Or, beware, poisonous snakes in area.
Be ware. Be aware. Be wary—cautious—concerned. LOOKOUT! This short passage at the tail end of Acts 12 should be a big blinking BEWARE sign for us. It warns us of three pits each of us can trip into if we aren't on guard.
