"Jesus beheld in Science the perfect man, who appeared to him where sinning mortal man appears to mortals. In this perfect man the Saviour saw God's own likeness, and this correct view of man healed the sick." "Hold thought steadfastly to the enduring, the good, and the true, and you will bring these into your experience proportionably to their occupancy of your thoughts." Here, in these two quotations from "Science and Health with Key to the Scriptures" by Mary Baker Eddy (pp. 476, 477, and p. 261), we have perfect rules for healing the sick.
In other words, regardless of what the material senses seem to present, our work is so to bring our thought in line with spiritual truth that we shall see the perfect man, the only one there really is, the one whom the Bible says God created "in his own image, in the image of God created he him" (Gen. 1:27). We do this as we refuse to repeat error, hear error, or see error or imperfection as real anywhere, in anyone or anything. This may seem like a big order, but just as a pianist, singer, craftsman, or artisan attains perfection only by practice, so we too, with an earnest desire for Truth, can eventually attain this state of thought by practice. The number of minutes and hours during the day that we entertain spiritual truths and think right thoughts measures our practice of Christian Science.
This impersonal work, or practice, is of the utmost importance. As we silently declare the perfection of the real universe, we are helping to lessen the bonds of others through the unfoldment of the truths of Christian Science. How rewarding it is to feel that thought imbued with Truth helps to liberate mankind.
