How many miracles are there in the novel Peace Like a River by Leif Enger?

I am currently writing an essay about the symbols shown in the novel, but as I took notes I began to realize that Land's father symbolizes Jesus Christ; then I noticed that Reuben Land represents the twelve disciples. However, I am reluctant to actually begin to write about that (Reuben symbolizing the disciples) because I don't actually remember how many miracles there were in the novel. Please help ><
