Christian Science shows the great importance of watching our thinking so that our thoughts and deeds are always in perfect agreement with the law of God. By casting the weight of our thinking on the side of God, we find that there is no other side in God's scale, for He, Mind, is All, and there is no matter.
In "Science and Health with Key to the Scriptures" Mary Baker Eddy uses the metaphor of scales to bring out the great importance of being right with God and always alert to the falsity of sense testimony. We read (p. 168): "If the scales are evenly adjusted, the removal of a single weight from either scale gives preponderance to the opposite. Whatever influence you cast on the side of matter, you take away from Mind, which would otherwise outweigh all else. Your belief militates against your health, when it ought to be enlisted on the side of health. When sick (according to belief) you rush after drugs, search out the material so-called laws of health, and depend upon them to heal you, though you have already brought yourself into the slough of disease through just this false belief."
Jesus taught that the power of God cannot be weighed in the scales of matter. He said (Matt. 6:24): "No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon." Material sense testimony can give no hint of the truth of God and His idea, man, for the vision of spiritual reality can be gained only through spiritual understanding. Strict adherence to Godlike qualities of truthfulness, purity, fidelity, justice, love, and tenderness provides the foundation stones upon which to build happy, successful, harmonious lives.
