Among the followers of the Master, John is known as the beloved disciple, and his words and life indicate why he was loved. Sitting at the feet of Jesus, he caught perhaps more clearly than all the others the essential quality of the Christ as demonstrated in Jesus' life and works. He must have seen that divine Love was the animus of all that the Master said and did. He seemed to have grasped the basic fact expressed in Jesus' teaching, and he must have in a measure lived that Love himself, for he wrote (I John 4:11-16): "Beloved, if God so loved us, we ought also to love one another. No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.... And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him."
When the revelation of the promised Comforter, or Christ, appeared to Mary Baker Eddy, the same love that characterized the life and mission of Christ Jesus and his disciples found full expression in her thought and was the spiritually motivating force that impelled her to give her revelation of the truth of being to mankind and record it in the textbook, "Science and Health with Key to the Scriptures."
Speaking of Love, Mrs. Eddy says in her book "Miscellaneous Writings" (pp. 249, 250): "What a word! I am in awe before it. Over what worlds on worlds it hath range and is sovereign! the underived, the incomparable, the infinite All of good, the alone God, is Love."
