Paul the Apostle spoke a great truth regarding man's environment when he said (Acts 17:28), "In him [God] we live, and move, and have our being." When rightly understood and applied, the liberating truth expressed in those words will bring healing and restoration through the elimination from consciousness of false concepts—concepts which, like shadows, may seem to stand between an individual and his enjoyment of that all-good environment which is his God-bestowed heritage.
A fuller understanding of the true environment of man may be gained through a thoughtful study of the definition of God on page 465 of the textbook of Christian Science, "Science and Health with Key to the Scriptures" by Mary Baker Eddy: "God is incorporeal, divine, supreme, infinite Mind, Spirit, Soul, Principle, Life, Truth, Love."
The Bible often puts emphasis on the truth that God is Spirit. Obviously then man, the image and likeness of Spirit, is spiritual, and therefore is not subject to hurt, injury, or lack of adjustment. Obviously also, his environment is not only all good, but also spiritual; and acceptance of this truth precludes the belief that man lives in a material environment and is beset by various kinds of dangers and imperfections from which he can escape to a faraway perfect environment (the conventional heaven) only through the door of death. As the result of fallacious thinking, disease, injury, and discord may seem to be present in one's environment, but they will disappear as one substitutes the understanding of Truth for false concepts.
