The Apostle, who has set forth the character of the Christian's election, who has given to the converts large assurance for the hope which he exhorts them to hold, who has proclaimed the exceeding glory of their inheritance in the future and how its nature had been foreshadowed in type and prophecy, now turns to those practical lessons which he would enforce from the doctrines of election and of the future glory in heaven. Such glorious privileges cannot be looked forward to without awakening a sense of corresponding duties, and for these he would not have them unprepared. _Wherefore_, he says, because you have the assurance of what the best men of old only dimly foresaw, _girding up the loins of your mind, be sober_. The Apostle has in mind the words of his Master, "Let your loins be girded about, and your lamps burning; and be ye yourselves like unto men looking for their lord" (Luke xii. 35, 36). The advent of the bridegroom may be sudden; those who would be of his train must be prepared for their summons. To be girt in body is a token of readiness for coming duty. And St. Peter's figure would speak more forcibly to Eastern ears than it does to ours. Without such girding the Oriental is helpless for active work, the encumbrance of his flowing robes being fatal to exertion. The heart of the Christian must be untrammelled with the cares, the affections, the pleasures of the world. He must be free to run the race which lies before him, as was the well-girt prophet who ran before the royal chariot to the entrance of Jezreel.
