One of the most powerful aspects of Christian Science is its profound simplicity. Unfortunately, we frequently lose sight of this simplicity, or obscure it, because in our human efforts to "learn" this Science, and to live it, we tend to picture it as a complex array of individual "truths" to be acquired and "mastered," rather than one integrated, seamless whole.
This tendency of the human mind could well be part of what the Apostle Paul was concerned with when he wrote, "But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ." II Cor. 11:3. Our great need is to reject this corrupting influence of the so-called mortal mind—the erroneous belief that mind is in matter and is capable of both good and evil—and accept "the simplicity that is in Christ."
When thought dwells in this Christly simplicity, one begins to glimpse the fact that all that Christian Science teaches derives from, and is embraced in, the simple truth that God is All, and this allness includes His spiritual creation, man and the universe. He is all the Life there is; all the Truth; all the Love; the one Spirit; the only Soul; the all-causative Principle. He is the only Mind, or consciousness, of man. Nothing really exists outside of what God is knowing or is conscious of.
