The good work begun will be finished; the holy thoughts, heavenly affections, and Christlike actions will take the place of impure thoughts, perverse sentiments, and rebellious acts. CH 561.1

Each one must fight his own battle against self. Heed the teachings of the Holy Spirit. If this is done, they will be repeated again and again until the impressions are as it were “lead in the rock forever.” ... CH 561.2
