You and I wouldn't be happy with Christian Science if there wasn't something more to learn. If we could actually come to the end of the subject, where we knew all there was to know about it, we would have reached its limits—and our own! Having "learned it all," we would have nothing left to do, no way to extend and further improve ourselves.
Fortunately, such a situation is entirely imaginary. There's always more to know because Christian Science isn't an academic subject. There are no limits to what is to be learned of the infinite truths of God, man, and the universe. Do we, however, sometimes place ourselves in the imaginary situation? Do we assume consciously or unconsciously that we have essentially come to the end of our learning?
Perhaps, for example, we have been Christian Scientists for some years, active in branch church work, faithful students of the Lesson-Sermon. After all, we aren't beginners!
