Before Mrs. Eddy discovered Christian Science it would have been the height of folly for anyone to question the reality either of sin or disease. But since then a noticeable change has taken place in the experience of those who accept her discovery as revealed truth. Of course this Science does not base its denial of the reality of these evils on mankind's experience with them. It could not do that. Rather, it denies the reality of both sin and disease on the basis of the allness of God, good. And it sets people to work to prove that as they spiritually understand the truth of this statement the tendency to sin or get sick lessens until the unreality of both sin and disease is scientifically demonstrated.
In fact, Christian Scientists find that as they understand both sin and disease to be deceptions rather than realities, they become less and less subject to them. This understanding reveals a way of overcoming these errors that promises to do more for the people than any other system has ever done or ever can do.
Mortal belief places upon a child a susceptibility to sin and disease the moment he is born. It is believed that he will naturally conform to a pattern of sin before he knows what sin is and submit to diseases that he knows nothing of. Then he is told that all through his life he must be on guard against sinning and becoming sick. It was to this universal belief that the Apostle Paul referred when he wrote to the Romans (7: 21), "I find then a law, that, when I would do good, evil is present with me." But education and experience need not condition us to accept this as a law.
