The working out of problems which to human sense appear insurmountable engages the attention of earnest Christian Scientists. It is an illuminating experience to apply the truth regarding man and his relationship to God, as taught by Mary Baker Eddy in "Science and Health with Key to the Scriptures." In this textbook she writes (p. 231), "If God makes sin, if good produces evil, if truth results in error, then Science and Christianity are helpless; but there are no antagonistic powers nor laws, spiritual or material, creating and governing man through perpetual warfare."
The first step, therefore, when one is confronted with a seemingly hopeless situation, is to change one's thought from a material basis to a spiritual one. Since there is only one supreme God, there can be only one all-powerful Mind, and that one good, directing and producing harmony in the spiritual realm. Since man, made in the image and likeness of God, is spiritual, he reflects harmony.
In affirming that God is conscious only of harmony, we begin to lose our fear, for we recognize that the evils testified to by material sense have no Principle; therefore they are powerless and unreal. The so-called laws governing mortal experience are liable to mutation and correction and so cannot dismay the one who, acknowledging only the perfection and power of his Maker, stands on a firm foundation. Little by little the false claims of power other than God are swept from consciousness. Thus we find that Mind is self-expressed and self-sustained, and, in the words of our Leader (ibid., p. 393), we "rise in the strength of Spirit to resist all that is unlike good."
