An opaque wall, a dirty window, or a clean, transparent pane of glass – which one will allow the sun to shine through best? Using this imagery, Mary Baker Eddy describes mortal thought, or material consciousness. She points out that the dark mortal thought, engrossed in materiality, is as dense as a solid wall; whereas, the mortal thought that is being spiritually enlightened by God becomes less restrictive, less material in basis, and more transparent and welcoming to the Christ light.
Here are her inspiring words from “Science and Health with Key to the Scriptures”: “The manifestation of God through mortals is as light passing through the window-pane. The light and the glass never mingle, but as matter, the glass is less opaque than the walls. The mortal mind through which Truth appears most vividly is that one which has lost much materiality – much error – in order to become a better transparency for Truth. Then, like a cloud melting into thin vapor, it no longer hides the sun” (p. 295).
Christ Jesus, the best example of the ideal, perfect man, humbly and lovingly provided us an illuminating window into his spiritual consciousness. He said, “The Son can do nothing of himself, but what he seeth the Father do: for what things soever he doeth, these also doeth the Son likewise” (John 5:19). He followed his clear explanation of the real origin and originator of his mighty works by promising that even greater works would be done by those who understand him in their demonstration of true Christianity.
Looking through this unencumbered transparency into the one Mind of Christ, we see ourselves as God’s spiritual, perfect creation, as the natural outgrowth of His infinite wisdom. Seeing ourselves in this light, we are cleaning our window of thought, allowing it to become more transparent, more receptive to Spirit, and this spiritualization of thought lets in the Truth which reforms and heals.
Once I received a call from a relative asking for prayer because he was suffering from intense pain. As I prayed, anchoring my thought in God’s reality, my attention was drawn to a towel hanging on a railing close by. As the porch swing that I was sitting on moved back and forth, it cast a shadow on the towel. When the swing moved away, the shadow disappeared. When the swing moved back, the shadow reappeared. The towel, however, was not affected in any way by the shadow.
I saw the towel as representing God’s perfect image and likeness, man. I saw the light as the Christ. I saw the shadow cast on the towel as evil or materially based thinking seeming to conceal or hide the perfect spiritual likeness of man. I saw the porch swing as representing the vacillating mortal thought with its changing and confused viewpoints of God and man.
This back-and-forth argument for good or evil would seem to cloud, deface, or even conceal the divine image of man. But this perfect image, as represented by the towel, is not altered by a shadow. Our identity as God’s child is permanent and solid reality.
I reasoned then that my relative could not be affected by the “valley of the shadow[s]” (Psalms 23:4) cast on him to make him fearful and believe he was material and subject to pain. He is always the healthy, spiritual image of God. The mortal view can have no voice and no authority, for that would be contrary to God’s perfect law. I knew this truth would relieve the troubled thought and bring healing. Within a short time my relative called and confirmed that he was free of the pain, and it didn’t return.
Divine Science is the Holy Ghost or Comforter, and it is clear and practical. The great freedom Christian Science brings elicits joy and gratitude. Good is manifested in our lives, and we cannot help but sing praises to God. As the last verse of a hymn says,
Then open wide your heart
To Truth and Light and Love;
You then shall know your life is hid
With Christ in God above.
(Charles Parsons, “Christian Science Hymnal,” No. 201)
It is the heart’s desire to clean the windowpane of thought to receive even more of the Christ. For as we do, the shadows of darkness, fear, and doubt fade away. The light streams in. We stand in the daylight of ever-present good, and all is bright and radiant around us.
