An alert professor brought to the attention of a class of university students the fact that marginal headings are of importance but are sometimes neglected. In introducing a new textbook to the class, the professor stated that this particular book would be the basis of instruction during the entire semester. He said that it was a serious work, but that there were no marginal headings; and he therefore strongly recommended that the students supply their own marginal headings, jotting down the essence of each paragraph in a few vital words.
The students who followed this excellent advice, establishing the little guideposts pointing to the author's meaning, not only gained a better understanding of the subject at hand, but learned to value marginal headings in other books.
Such was the experience of one student in this class who at that time was searching for a better understanding of God. She was introduced to the Christian Science textbook, "Science and Health with Key to the Scriptures" by Mary Baker Eddy. As she held this textbook in her hands for the first time, she paused a moment and earnestly prayed that it might be revealed to her whether this little book were indeed the gateway to an understanding of God, which its adherents claimed it to be.
