"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.
