CHRISTIAN SCIENCE teaches that man in God's image and likeness is deathless, eternal, and indestructible. It therefore denies the generally accepted belief that eternal life can be achieved only as the result of an experience called death.
The Bible clearly confirms the teachings of Christian Science regarding eternal and indestructible life and particularly in the following statements of Jesus (John 11: 26): "Whosoever liveth and believeth in me shall never die," and (John 17:3), "This is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent."
Mary Baker Eddy gives us this practical instruction on the subject of life eternal (The First Church of Christ, Scientist, and Miscellany, p. 242): "You can never demonstrate spirituality until you declare yourself to be immortal and understand that you are so. Christian Science is absolute; it is neither behind the point of perfection nor advancing towards it; it is at this point and must be practised therefrom. Unless you fully perceive that you are the child of God, hence perfect, you have no Principle to demonstrate and no rule for its demonstration."
