Men have their choice in this world. They can be angels, or they may be demons. In the apocalyptic vision, John describes a war in heaven. You have only to strip that vision of its gorgeous Oriental drapery, divest it of its shining and celestial ornaments, clothe it in the simple and familiar language of common sense, and you will have before you the eternal conflict between right and wrong, good and evil, liberty and slavery, truth and falsehood, the glorious light of love, and the appalling darkness of human selfishness and sin. The human heart is a seat of constant war... Just what takes place in individual human hearts, often takes place between nations, and between individuals of the same nation.
