We all love the message with which Christ Jesus comforted his disciples when he said (John 14:27), "Let not your heart be troubled, neither let it be afraid."
In the Bible, as in present-day literature, the word "heart" is frequently used to signify one's innermost thoughts or feelings, one's mental attitude. Surely it was to his followers' mental attitude, not to the physical heart, that Jesus referred.
In her writings Mrs. Eddy often uses the word "heart" in like manner. In Science and Health she gives a definition of this word that separates it from the physical and puts it into the humanly mental. The definition reads (p. 587): "Heart. Mortal feelings, motives, affections, joys, and sorrows." Christian Science makes clear that we need to be alert to mortal feelings, mortal elements, finding place and activity in human consciousness; for it is mortal thought, with its misconception of God and man, not the physical organs of the body, that opens the door to sickness, sin, and death. Confused mortal beliefs must yield to the divine logic of perfect Principle and perfect idea if we would keep ourselves free from mental vexations and bodily ailments.
