It is the special work of Satan in these last days to take possession of the minds of the youth, to corrupt their thoughts, and inflame their passions. All are free moral agents, and as such they must bring their thoughts to run in the right channel.... If Satan seeks to divert the mind to low and sensual things, bring it back again, and place it on eternal things; and when the Lord sees the determined effort made to retain only pure thoughts, He will attract the mind, like the magnet, and purify the thoughts.... The first work of those who would reform is to purify the imagination. If the mind is led out in a vicious direction, it must be restrained to dwell only upon pure and elevated subjects. When tempted to yield to a corrupt imagination, then flee to the throne of grace, and pray for strength from Heaven. In the strength of God the imagination can be disciplined to dwell upon things which are pure and heavenly.... (OHC 337.3) MC VC
