Here to the converts, exposed to the assaults of these temptations, he enjoins the same well-ordered frame of mind which before (i. 13) he commended to them as they looked forward to the hope in store for them, and also (iv. 7) in their prayers, that their petitions might be such as suited with the approaching end of all things. _Be sober_, he says again, and combines therewith an exhortation which without sobriety is impossible: _Be watchful_. If the mind be unbalanced, there can be no keeping of a true guard against such dangers as were around these struggling believers. And it is impossible not to connect such an exhortation from his lips with those words of Christ, which one Evangelist says were expressly addressed to St. Peter, "Watch and pray, that ye enter not into temptation" (Mark xiv. 37, 38). He who had received this admonition was conscious that, as in his own case, so with these his converts, the spirit might be willing, but the flesh was weak, and the enemy mighty. _Your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour._ In the days of Job, when God asked of Satan, "Whence comest thou?" his answer was, "From going to and fro in the earth and from walking up and down in it" (Job i. 7). Of this Old Testament language the Apostle here makes partial use in his description of the enemy of mankind. He walketh about in the earth, which is his province, for he is called the prince of this world (John xii. 31) and the god of this world (2 Cor. iv. 4). And the Greek word ἀντίδικος, "adversary," which St. Peter uses as a translation of the Hebrew "Satan," is well chosen, for it describes not an ordinary enemy, but one who acts as an opponent would in a court of law. Such was Satan from the first, an accuser. In Job's case he accused the Patriarch to his God: "Doth Job serve God for nought?" "Put forth Thine hand now, and touch all that he hath, or touch his bone and his flesh, and he will curse Thee to Thy face." In earlier days he appears as the accuser of God Himself: "Ye shall not surely die, for God doth know that in the day ye eat thereof then your eyes shall be opened, and ye shall be as God, knowing good and evil" (Gen. iii. 4, 5). And with such-like suggestions he assails the faithful continually, speaking either to their unguarded hearts, or by the words of his servants, of whom he has no lack. St. Paul dreaded his power for the Thessalonian converts: "I sent that I might know your faith, lest by any means the tempter had tempted you, and our labour should be in vain" (1 Thess. iii. 5). And St. Peter's words are dictated by the same fear; he has the same wish to keep the flock steadfast in their faith. To them Satan's whisperings would be after this sort: "You are forgotten of God"; "Love could never leave you so long in trial." Or his agents would say in scorn, "How can you talk of freedom, when your life is one long torment? What is the profit of
