How often we hear the expression "I've had a grand day!" What does it mean? Essentially that good has appeared and been experienced. Inasmuch as experience is always thought externalized, a grand day begins in our thinking. When our thought is illumined and spiritualized, we are certain to have many grand days—teeming with achievement, too.
To experience greater good is truly to progress, and every normal human being desires to improve. Naturally, nothing can improve divine Mind, which is infinite and perfect. Nor does God's spiritual idea, man, need to improve. He is already perfect and complete. But progress on the human scene does simulate, in a degree, the divine sense of unfoldment, or "day," Mrs. Eddy's definition of which reads in part: "The objects of time and sense disappear in the illumination of spiritual understanding, and Mind measures time according to the good that is unfolded. This unfolding is God's day, and 'there shall be no night there.'" Science and Health, p. 584;
We can make God's day our day by accepting the true sense of unfoldment and living it. Christian Science enables us to see more and more clearly that, from the absolute standpoint, God's creation is finished and complete. Yet it is active, ever unfolding from the limitless basis of infinity. This unfoldment is always taking place in divine being, which is eternally expressing itself. Of course, we are interested in understanding this unfoldment of good because in the degree that we understand it we can demonstrate it in our human experience.
