In "Science and Health with Key to the Scriptures" Mary Baker Eddy writes (p. 113): "The vital part, the heart and soul of Christian Science, is Love. Without this, the letter is but the dead body of Science,—pulseless, cold, inanimate."
A dictionary defines "vital" thus: "Being the seat of life; being that on which life depends." A true understanding of divine Love would, then, bring with it a truer understanding of Life, God. In the consciousness of divine Love's all-presence no devitalizing elements of hatred or fear are found, for the nature of divine Love precludes the possibility of anything unlike Love ever entering its presence.
The activity of divine Love is effortless, spontaneous, and free. It encounters no obstacles or delays, for everything unlike Love fades before the might of Love. To love is to have no consciousness of a sick or sinning man, to entertain no limitation or greed, to think of no evil as real, to hear no evil except to correct it, to voice no evil. To one who understands divine Love comes the realization that there is no injustice, no frustration, no lack of fruition.
