I saw much evidence of God’s eternal light in “Evidence of Things Unseen.” But for the most part, the characters do not recognize God or even fate in the events that culminate in the death of Fos and Opal and in the placing of Lightfoot in a “Foster” home. Fos caused Opal’s death with his amateur science, the Oak Ridge facility probabaly caused Fos’ radiation sickness, and Lightfoot was about to be taken away because they didn’t arrange for a birth certificate when he was small.
Never does Fos ball his fist against God or scream his anger. He does not fall to his knees and pray a higher power for the lives of his wife and son. In their moment of crisis, Fos thinks of praying, but he feels that he cannot, and that is incommunicative father is to blame. Even though he cherishes and appreciates it, he accepts their wonderful love not as a gift, but as a given. And even though Fos spent a lifetime studying, pondering, watching luminesences of all kinds, he never saw the light of God behind those phenomena. The highest he could go was the material that the stars were made of, and Opal wouldn’t even buy that.
I was looking forward to find God in the unseen light behind the bioluminesence, but even in the midst of one of the most beautiful love stories I’ve ever read, the Unseen Light turned out to be a lump of phosphorus in a fish bowl. The saving grace is that the more spiritually inclined reader will be able to recognize the divine nature of Fos and Opal’s love despite the characters and even the author’s protestations (“Fools, when their roof tree falls, think it’s Doomsday …”)
