Isaiah 42:6,7 I the Lord have called thee in righteousness, and will hold thine hand, and will keep thee, and give thee for a covenant of the people, for a light of the Gentiles; To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house. Science and Health 215:15-18 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.
