Remembering and forgetting: two important concepts. It's vital to know, though, just what we should remember—and what we ought to forget. And, paradoxically, to remember what is still true, even when we seem to have forgotten it!
Christian Science is an immense help in defining the issue in practical ways. For instance, Science and Health says, "The issues of pain or pleasure must come through mind, and like a watchman forsaking his post, we admit the intruding belief, forgetting that through divine help we can forbid this entrance." Science and Health, pp. 392-393. That is a significant "forgetting," and a needless one.
Whether we're new to Christian Science or longtime students, it's more than useful to study the letter of the teaching often and alertly. Why? Partly because we tend to forget its essential points. No matter how sincere we are, in the hurly-burly of modern life or the gush of business activity it seems we can sometimes readily overlook scientific, spiritual facts—for example, the fact that there is neither intelligence nor identity in matter, and that we are spiritual and enduringly perfect as God's emanation. Nevertheless, God is all-knowing Mind, and His knowing is with us hour to hour, and permanently. And such scientific thoughts remain true—in this moment and forever. That they may seem to slip out of our notice temporarily, and our perception of them get as fogged up as windows on a frosty morning, doesn't alter their validity. As we return to them, we again find their power.
