It is the duty of every one to live up to his highest understanding of Good. A Christian Scientist, by studying the Science of Being, finds this understanding to be higher, clearer, and broader every day; so the inevitable demand for a better life follows. The understanding can come only by a careful study of the Science of Mind, the laws of God, as expressed in His universe. There is no science of matter. Material knowledge is but an investigation of shadowy things based upon a supposition (which supposition has never been proven), and these theories arranged, classified, and put into operation by a so-called material law.
The more evil is analyzed and dissected, the more its nothingness appears; it is elusive and illusive, fleeing before the light of Truth. On the other hand, the more Good is investigated the more its somethingness becomes apparent, for it is the only Substance there is.
The understanding and demonstration of Good can only come to one who is honestly endeavoring to lift his thought above matter and its laws, and learn its opposite. Hence, Jesus' metaphysical statement, "Blessed are the pure in heart: for they shall see God,"—blessed are the pure in thought, believing in but one power, even Spirit, for they shall discern the Principle of Goodness.
