Mankind, enlightened spiritually, has long sung praises of God's goodness. The Bible is full of the praises of the Lord. Kings, prophets, people, all have praised the Lord for His goodness. We read in the book of Genesis: "And God saw every thing that he had made, and, behold, it was very good."
Mrs. Eddy says in "Science and Health with Key to the Scriptures" (p. 119), "God is natural good, and is represented only by the idea of goodness; while evil should be regarded as unnatural, because it is opposed to the nature of Spirit, God." God—Life, Truth, and Love—includes all goodness, and this goodness is to be found everywhere. The understanding of the actuality of Being destroys the false belief of evil, including sickness, sin, and death. By carefully studying Science and Health we learn that goodness is the very essence of Life, and that it should be the underlying motive of all the undertakings in our existence. Goodness carries with it the elements of divine impulsion, law, and government; and this understanding gives the assurance of both health and success. The allness of good necessitates that its unlikeness, evil, be recognized as a lie, and brings its imaginary existence to naught, thus preventing it from even seeming to govern.
On page 113 of Science and Health Mrs. Eddy writes: "1. God is All-in-all. 2. God is good. Good is Mind. 3. God, Spirit, being all, nothing is matter. 4. Life, God, omnipotent good, deny death, evil, sin, disease.—Disease, sin, evil, death, deny good, omnipotent God, Life. Which of the denials in proposition four is true? Both are not, cannot be, true. According to the Scripture, I find that God is true, 'but every [mortal] man a liar.'" Christian Science thus teaches how to affirm the allness of good, and how to develop goodness. It also teaches us how to challenge, discredit, deny, and nullify evil, which is always unreal, a negation claiming to be something. When we clearly understand the above scientific statement of Mrs. Eddy, we shall find that errors of belief will cease to occupy and entangle our thoughts and to fetter our bodies.
