Christian Science reveals the nature of God as wholly good. Indeed, good is used by Mary Baker Eddy as a synonymous term for God. She defines "good" in the Glossary of "Science and Health with Key to the. Scriptures" as follows (p. 587): "God; Spirit; omnipotence; omniscience; omnipresence; omni-action." Goodness is not, therefore, a human quality, but a divine attribute. It is essential to our progress in Christian Science that we understand this fact clearly, else we may drift into the common belief that good is merely a moral quality, liable to loss or reversal.
Good is God, irreversible, indestructible, and ever present. Notice how Mrs. Eddy defines the word good by reference to an all-embracing power, knowledge, presence, and activity. Goodness is the nature, substance, and constitution of God's creation. The true man and the true universe are wholly good. Our relationship to good must be established through the Christ by spiritual understanding. As mortals we know very little of the all-acting, all-wise, all-powerful, and omnipresent good. And yet as we dwell upon the truth of God as wholly good, and of man's inseparability from God, we begin to feel this eternal divine order and wholly beneficent presence of God as expressed in active good and in numberless blessings within our human experience.
When good has found expression in our lives as the result of our communion with God, we have glimpsed the Christ, or divine manifestation. Christ Jesus described himself as the good shepherd. He said (John 10:14), "I am the good shepherd, and know my sheep, and am known of mine." The Master was good because he knew God. There was no reason for the goodness he expressed other than the fact that he was conscious of God's presence, power, and goodness, and of his true selfhood as His reflection. He constantly claimed his inseparability from God, or good. He said (verse 30), "I and my Father are one."
