I once had a very painful and swollen foot. I couldn't even step on it. There was no evidence on the outside showing injury or any reason for the difficulty. I couldn't recall having injured it in any way.
After days of misery and inability to walk on this foot, one morning I noticed in the Lesson-Sermon from the Christian Science Quarterly this statement of Mrs. Eddy's: "Nothing inharmonious can enter being, for Life is God." The full quotation is: "The transmission of disease or of certain idiosyncrasies of mortal mind would be impossible if this great fact of being were learned,—namely, that nothing inharmonious can enter being, for Life is God." Science and Health, p. 228; Instantly a sense of healing went all through me. The next morning there was a sharp piece of hard black rubber just under the skin on the bottom of my foot. I then recalled that weeks back I had stepped on something sharp in our apartment but had brushed my foot off and thought nothing more of it. Evidently when a light fixture had been repaired, this little piece of sharp, hard rubber remained on the floor.
I realized that one of the anxieties and fears of mortal mind is that inharmonies can actually enter one's being. But they simply cannot. Man's sonship is kept intact by the Father. It is impenetrable. It is uninvadable. And there is nothing to penetrate or invade it. This realization expelled the foreign matter from my foot. The truth expressed in Mrs. Eddy's statement, quoted above, did the job. This precious realization can protect one from contagion of any nature. It can immunize him from so-called contagious disease or from the daily and hourly temptation to be affected by the multitude of false concepts constantly confronting him.
