We do not know when our day of judgment will come, when our nations will rise or fall, or when the times of testing in which we are either proven or broken will hit us. Yet Peter exhorts us to be found ready in vigilant holiness when they do.
Perhaps the kind of wakefulness that Christ is calling us to in anticipation of his coming is a wakefulness to the urgent cries and needs of one another. Perhaps Christ is calling us to truly recognize one another before we will be able to recognize God in our midst.
