A "Career" originally meant a "racecourse," and hence came to mean a progressive course of action of an individual or a nation. Absolutely speaking, the course of action, or career, of man is to express the Divine Being, for man is the reflection of Life, Truth, and Love. As the infinite idea of infinite Mind, man is forever reflecting unfolding good, embracing all right ideas, which are endlessly developing and forever appearing from their inexhaustible source.
Mary Baker Eddy writes in "Miscellaneous Writings" (p. 82): "Man is the offspring and idea of the Supreme Being, whose law is perfect and infinite. In obedience to this law, man is forever unfolding the endless beatitudes of Being; for he is the image and likeness of infinite Life, Truth, and Love." What greater or more glorious career could man have than this, to be the eternal witness, or outcome, of Mind's infinite unfoldment and self-expression? Nothing can interrupt or frustrate this eternally progressive activity, for nothing exists except Principle and its idea—Mind and all that Mind knows of itself.
Man is not a finite human being struggling to carve out a career in material surroundings. He is the spiritual expression of Mind's infinite unfoldment. Since Mind and its ideas are all that exist, the eternal unfoldment of Mind can never be subject to interruption. The more clearly human consciousness perceives this truth and the more the spiritual fact of being permeates thought, the closer will the human sense of career pattern the divine, and earthly experience will become more orderly, progressive, and satisfying. The more the changeless spiritual nature of existence is understood, the less will the vagaries of mortal mind be evidenced. In Science, man is forever governed by divine Principle alone.
