Included in the prophet Ezekiel's record of the vision of God that came to him is this lovely description (1:28): "As the appearance of the bow that is in the cloud in the day of rain, so was the appearance of the brightness round about. This was the appearance of the likeness of the glory of the Lord."
Sometimes when an observer stands between tiny droplets of water and the sun, he sees a rainbow in the sky. The little particles of moisture act as a prism, dividing the rays of white sunlight and showing the colors seen in the rainbow. There is no color in the prism. The color is the light and only becomes apparent when the light is divided. The prism does not add anything to the light, nor does it take anything away. All the colors together make white light, and each ray of white light includes all the hues of the spectral range.
For centuries Christians have rejoiced in the bright sunlight of faith and hope in God, in His changeless goodness and impartial mercy. But without the Science of Christianity they have not been able to perceive the full import and all-inclusive nature of God. The clear prism of scientific understanding has been needed to divide the all-embracing light of God's revelation of the Christ-idea and of the healing power it makes manifest to humanity. The prophet Ezekiel, in speaking of "the likeness of the glory of the Lord," evidently glimpsed in some measure the significance of the Christly effulgence.
