Which part of this excerpt from Leo Tolstoy’s The Death of Ivan Ilyich suggests that Gerasim's acceptance of death is related to his spirituality?
There was no one in the anteroom, but Gerasim darted out of the dead man's room, rummaged with his strong hands among the fur coats to find Peter Ivanovich's and helped him on with it.

"Well, friend Gerasim," said Peter Ivanovich, so as to say something. "It's a sad affair, isn't it?"

"It's God will. We shall all come to it some day," said Gerasim, displaying his teeth—the even white teeth of a healthy peasant—and, like a man in the thick of urgent work, he briskly opened the front door, called the coachman, helped Peter Ivanovich into the sledge, and sprang back to the porch as if in readiness for what he had to do next.
