Im going to take much of what youve offered and incorporate that into the framing of the scene.
Lets reduce the accomplishment to: I hope I show my superior understanding of the Book of Life to Sis. Miriam.
Who knows, maybe your character will prove even a greater understanding of the scripture than Sis.Miriam. Lets put it to the dice and find out.
You, Ezra and Miriam have been fasting for several days. It is a bleak, cold, early winter evening. The first snow storms of the season are still weeks or days away. The red rocks of the valley glow a sickly orange-yellow, as the sun sets behind gray clouds. You are all out walking, far from Bridal Falls. Each of you knows it will be dark before you get back.
As Sis. Miriam turns around, guiding your return to Bridal Falls she stops, opens her dry and delicate copy of the Book of Life and reads: "They have sown the wind, and they shall reap the whirlwind."
A gust of sand and wind, mixed with leaves ushers past your feet.
I feel a terrible winter approaching, my brothers. What wind have we sown? she asks. She looks sad, as though carrying a heavy guilt.
