The Holy Bible, KJV, Psalms 91
We are sometimes led to believe that darkness is as real as light; but Science affirms darkness to be only a mortal sense of the absence of light, at the coming of which darkness loses the appearance of reality. So sin and sorrow, disease and death, are the suppositional absence of Life, God, and flee as phantoms of error before truth and love.
Science and Health by Mary Baker Eddy, pg. 215
