There is a universal belief that the measurement of a man's life must be in terms of years, that man is a mortal, experiencing birth, growth, maturity, old age, and decay. The teachings of Christian Science show that this belief need not be accepted, for it is not actually a law governing man. This Science teaches that man, the reflection of Life, God, is undying and immortal.
A student of Christian Science soon learns that senility is an error, not a fact, and that he must not allow himself to believe in decrepitude or old age. He learns that the passing of time has nothing to do with his real selfhood, the reflection of the Life which is God. As the years come and go, he should advance in experience, wisdom, and a greater understanding of God. Thus the thought of advancing years will indicate progress and unfoldment, not decline or infirmity.
Sometimes one hears the expression "the evening of life," meaning the declining period of a person's life or old age. Man, whose immortal selfhood has nothing to do with the passage of time, lives in the eternal now. So any sense of the "evening of life," with its mortal beliefs and implications of weakness and imperfection, does not apply to the real, spiritual man.
