In answering the question "What is Life?" in Science and Health, Mary Baker Eddy writes: "Life is divine Principle, Mind, Soul, Spirit. Life is without beginning and without end. Eternity, not time, expresses the thought of Life, and time is no part of eternity. One ceases in proportion as the other is recognized. Time is finite; eternity is forever infinite." Science and Health, pp. 468-469
In the Glossary of the same book, time is defined in its metaphysical sense as "mortal measurements; limits, in which are summed up all human acts, thoughts, beliefs, opinions, knowledge; matter; error; that which begins before, and continues after, what is termed death, until the mortal disappears and spiritual perfection appears." Ibid.,p.595
Does this mean that we must die before we can overcome the limits imposed by the concept called time? No, it doesn't, because our true being is right now the perfect reflection of divine Life—eternal, untouched by time—and we don't have to wait to begin to prove this.
