Watch

Christ sums up his discussion of the end times and his return by repeating to his disciples what he wants them (and all the rest of his followers) to do: "And what I say unto you, I say unto all, Watch" (Mark 13.37).

We notice that Christ's summary is clearly not directed only at the disciples to whom he is speaking. He speaks these words to all. I am tempted to say that by all, he meant every person, because, even those who were not his followers, and who did not believe in him would be affected by Christ's return. Most likely it was a comment directed at all of his followers.

Watch means "to stay awake or be watchful," or "to be on the alert." It's pretty clear that here Christ means for his followers to be on the alert for his coming. They ought not to be taken by surprise. For we who follow Christ two thousand years later, the application is no different. We ought to be on the alert for, pray for, be expectant for, Christ's return.
