SO accustomed have mortals become to viewing certain forms of matter as solid that they may seldom think of this descriptive term "solid" as capable of being applied to Spirit. But in Christian Science the mortal sense of things is reversed. Matter is found to be insubstantial, because destructible. Spirit is found to be substantial, because eternal. Spirit is found to be solid and infinite, with no vacuum or space unoccupied by the essence of Spirit, divine intelligence.
A dictionary defines the word "solid," in part, as "having no vacant interspaces." When we accept this definition and acknowledge Spirit to be omnipresence, as the Bible teaches, the solidity of Spirit becomes comprehensible.
To the layman, matter in many of its forms seems solid. Yet the physical scientists tell us that, far from being solid, much of what appears to be the bulk of matter is space. Compressed to its most solid form visible to the eye, even microscopically, what is termed matter becomes only a fraction of its former size. Could this take place if matter were in fact solid?
