If Spirit exists at all, it must be infinite, for we cannot conceive of Spirit being confined within boundaries of any kind. Mind, Love, Truth, Life—all these terms are synonyms for God, and Christian Science shows us that God is everywhere expressed.

Mrs. Eddy states, "All is infinite Mind and its infinite manifestation, for God is All-in-all." ^{Science and Health, p. 468.} Since there can be no real opposite to infinite Mind, nor any real absence of Mind and its pure ideas, what appears to the material senses (which are always ignorant of reality) is not an entity but an illusion, a counterfeit of the true something.

Christian Science, through spiritual education, inspiration, and illumination, enables us to replace material illusions with divine fact. When we intelligently acknowledge God's allness, consciousness becomes illuminated with the Christ, Truth, which dispels darkness—or mortal thought. The Christ reveals to us what is really there all the time: the perfection that God, Mind, is expressing everywhere.

Healing occurs through such enlightenment, but healing is really a change of consciousness. The improvement or disappearance of a discordant material state is the outward effect of this change as it appears to human thought.

Mortal mind—thought that is ignorant of Truth—progressively dissolves through the spiritual illumination resulting from prayer. Inasmuch as there can be no blanks or gaps in infinite Mind, there cannot be any desolation or dearth of intelligence anywhere, at any time. Mrs. Eddy explains: "In divine Science, which is the seal of Deity and has the impress of heaven, God is revealed as infinite light. In the eternal Mind, no night is there." ^{Science and Health, p. 511.}

Matter and its concomitants of fear, sin, evil, are not realities. They are only seeming absences of God. Mrs. Eddy writes: "Speak the truth to every form of error. Tumors, ulcers, tubercles, inflammation, pain, deformed joints, are waking dream-shadows, dark images of mortal thought, which flee before the light of Truth." ^{Ibid., p. 418.}

If consciousness is filled with spiritual ideas, specific "dark images" appearing as evil or disease cannot deceive us into accepting their existence, nor can they persist. They disappear through the recognition of God's infinite perfection, including man as His reflex image.

This is illustrated in a healing our daughter had of a tooth cavity. A filling fell out, leaving a hole that could be felt, seen, talked about. This occurred during the time she was taking class instruction in Christian Science. When she visited a dentist afterward, no cavity could be found. Her consciousness had been so filled with Mind's ideas during class instruction that the cavity disappeared simultaneously with the disappearance of whatever needed correcting in her thought.

Christianly scientific healings obviously are not circumscribed by biological or physiological processes. Christ Jesus must have maintained a consistent elevation of thought in order to perform the mighty works he did through the power of Mind. That same Mind is our one true Mind, in which there is no darkness.

"Do not I fill heaven and earth? saith the Lord." ^{Jer. 23:24.}
