A favorite fictional character of mine used to tap his temple, squint his eyes, and commend himself for “dip t’inking!” The stories always showed his definition of deep thinking to be an amusing one, but he was certainly right to value it and want to practice it.
The Bible says: “Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him. But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God” (I Cor. 2:9–10)
Mary Baker Eddy has only one reference in her published writings to “the deep things of God.” It’s the title of an article in her book Unity of Good. After opening the article with several paragraphs that address the profound and irreconcilable differences between spiritual and material perspectives, she makes the statement, “Christians are commanded to grow in grace” (p. 14) In her main work, Science and Health with Key to the Scriptures, Mrs. Eddy wrote: “Jesus of Nazareth was the most scientific man that ever trod the globe. He plunged beneath the material surface of things, and found the spiritual cause” (p. 313) It’s easy to follow her connection of growth in grace with the need to see that spirituality is attained through effort and begins with the quality of depth, getting beneath the material surface of things, cultivating deeper thought processes.
