"Dost thou 'love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind'?"
This question stops me in my tracks every time I think of it. It forces a sober self-examination of my willingness to sacrifice everything for God and for Christian Science, the greatest system of ideas that mankind will ever need or know. This inescapable question is posed by Mary Baker Eddy in the opening chapter of Science and Health with Key to the Scriptures (p. 9). It was first articulated by Moses, in the Bible, as God's requirement for man, and it later appears in the Gospels in Jesus' answer to the scribes' question regarding "the first commandment of all" (see Mark 12:28–30).
Moses, Jesus, and Mary Baker Eddy: Each in differing ways could be said to be supporting pillars of the spiritual development of humankind. Their living responses to this greatest commandment forever altered the course of human thought. And they each voiced the same moral urgency indicating that something as great and profound and lasting as this commandment demands our heeding it, too, no matter how many years have passed.
