But the understanding of scripture is what we need, to restore the harmony of being and gain its Principle, the Father’s house, where the prodigal returns, and the perfection of man appears. Christ said, “Believe me that I am in the Father and the Father in me, else believe me for my works’ sake”, i. e., understand that I am Intelligence, and not matter, and that Intelligence is God, (there is no evil Intelligence) else believe this for the demonstration it brings, healing the sick, and casting out error.  (Eddy, Mary Baker, Science and Health, 1^st Edition., p.260)  

     It shall be the duty of every member of this Church to defend himself daily against aggressive mental suggestion, and not be made to forget nor to neglect his duty to God, to His Leader, and to mankind.  By his works he shall be judged, -and justified or condemned.   (Eddy, Mary Baker, Manual, p.42)

       Divine Love: give me grace, meekness, understanding and wisdom for each hour of this day.   Mary Baker Eddy

     When matter or muscles claim, “I am tired,” let Spirit contradict this;  (Eddy, Mary Baker, Science and Health, 1^st Edition., p.201)

     After severe toil, we say, I am fatigued, naturally concluding the muscles have been overtasked and need repose; but our only safe and permanent method to overcome a sense of fatigue is to deny the ability of personal sense, to make us weary, and let mind triumph over matter, with the opposite argument that saith, I am not tired, for the “I” is Spirit, and not matter; bid the physical report depart, even as you would a temptation to sin. It is science, to put down the arguments of personal sense, with the higher ones of Soul.  (Eddy, Mary Baker, Science and Health, 1^st Edition., p.198)
