I know that he exists
our gross eyes
**Gross** meant 'thick, dense, dull' in the 1860s—not disgusting. She's saying our senses are too crude to perceive God, like trying to see through fog.
fond ambush
**Fond** = foolish (archaic sense). God's hiding isn't loving—it's a foolish trick, like a child's game of hide-and-seek that goes wrong.

Eyes **glaze** when they die—the moisture dries, leaving a film. The playful 'glee' literally freezes into a corpse's stare.
crawled too far
Jokes that **crawl** are like insects—they started small and harmless but have spread into something repulsive. The game metaphor collapses into disgust.
