At the end of Parable of the Sower, we find Lauren summarizing the service the Earthseed group is holding when they bury their dead—all the people Lauren's crew has lost along the way. Members speak out memories, quote Bible passages or Earthseed verses, and say bits of things about their departed loved ones. After that, they plant oak trees, sit around and talk, share a meal, and decide to name the place Acorn. After that, the book gives us the actual parable of the sower from the King James Version of Luke—which you can read about in our "What's Up With The Title?" section.
Okay, so what does all that mean? Well, what we're getting is a depiction of a place of refuge—hopefully one that will be long lasting. Throughout the novel, Lauren and her fellow travelers really haven't had many safe places to stay. There have been a few parks, sure, but even those were only transitory spots. Earthseed plans to stay at Acorn—you can tell, because they've planted trees. The book's final image, before the quoting of the Bible, is of this safe Acorn refuge place Lauren have company have all established together. It's really promising.
And then we get the Bible passage, which basically says that some of the seeds the farmer plants will grow and be successful. We've witnessed Lauren trying to spread Earthseed and failing, but we've just now had a picture of the success, Acorn. (Speaking of seeds…) And the Bible passage just caps off that victory by suggesting that yes, in the future, Lauren is going to have success.
