The apostle’s words were written for the instruction of believers in every age, and they have a special significance for those who live at the time when “the end of all things is at hand.” His exhortations and warnings, and his words of faith and courage, are needed by every soul who would maintain his faith “steadfast unto the end.” Hebrews 3:14. (AA 518.1) MC VC

The apostle sought to teach the believers how important it is to keep the mind from wandering to forbidden themes or from spending its energies on trifling subjects. Those who would not fall a prey to Satan’s devices, must guard well the avenues of the soul; they must avoid reading, seeing, or hearing that which will suggest impure thoughts. The mind must not be left to dwell at random upon every subject that the enemy of souls may suggest. The heart must be faithfully sentineled, or evils without will awaken evils within, and the soul will wander in darkness. “Gird up the loins of your mind,” Peter wrote, “be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ; ... not fashioning yourselves according to the former lusts in your ignorance: but as He which hath called you is holy, so be ye holy in all manner of conversation; because it is written, Be ye holy; for I am holy.” 1 Peter 1:13~16. (AA 518.2) MC VC
