In view of what some might consider a delay, a Christian could lose his sense of urgency and instead give priority to a comfortable lifestyle. Could you see that happening to you? If we followed this line of reasoning, we would be deceiving ourselves. We could ask ourselves, ‘Should it surprise me that this wicked system of things has lasted longer than I expected?' Why the repeated warnings? Such reminders are needed when as a result of waiting over what seems to be an extended period, people are at risk of losing their sense of urgency.
Oh jeez. They've been keeping up that "sense of urgency" for a century or more. They don't get it that one cannot be urgent forever without fatigue setting in.
What did Jesus say? He said he would be coming like a thief in the night. That means that it would come at a wholly unexpected time. When you are confortably at home, do you stay up all hours and sit constantly with a bat in hand waiting for that moment when a prospective thief will do some B&E? Is that how you are in your house every hour of every day of every week of every month of every year? No? The point is to be ready in case it ever happens, as there would be no time to prepare. The parable of the virgins has the same idea. They waited and waited for the bridegroom until they got tired and eventually fell asleep. ALL OF THEM, the wise AND the foolish virgins. Jesus recognized that you can't stay awake forever, it's impossible. Rest is a human need. So it wasn't foolish for them to fall asleep. Rather it was the lack of preparedness that made the five foolish virgins foolish. They had to leave in order to get their oil. The wise virgins waited until they fell asleep; they did not force themselves to stay awake and be sleepy when the bridegroom arrived. Rather they got the rest they needed but were ready to get up and get to work to greet the bridegroom when the time came.
A perpetual state of urgency can only make one tired. Do you GET IT, Watchtower?
