In the Christian Science textbook, Science and Health, Mrs. Eddy tells us that "a grain of Christian Science does wonders for mortals, so omnipotent is Truth, but more of Christian Science must be gained in order to continue in well doing." Science and Health, p. 449; Who does not wish "to continue in well doing"?
The above passage tells active students of Christian Science the condition of this continuing: to gain more of this Science. We gain more in any field of endeavor primarily by searching, studying, practicing, applying, and always being open to more new light.
In Christian Science, students may delve deeply into spiritual facts and begin to revise in human consciousness the conclusions which the world has accepted, for example, the reality of matter. By spiritual research we endeavor to discover that which is spiritually true. This can be one of the major ways of gaining more of Christian Science. Through this Science mankind has available the means for the most profound and meaningful research of all—that into the realm of the real, of infinite, inexhaustible Spirit. Mind's infinite supply of infinite ideas can never be depleted or used up because Mind's unfoldment of itself is perpetual and unlimited.
