Why are so many stories about people banding together in small, close-knit groups (or ones that become that way)? Even the brooding loners eventually join a team — Logan joins the X-Men, Ironman goes with the Avengers. This theme permeates writing, film and history, as John Eldredge writes in Waking the Dead:
When Neo is set free from the Matrix, he joins the crew of the Nebuchadnezzar…[and] the small fellowship [is] called to set the captives free…a family bound together in a single fate. Together, they train for battle. Together, they plan their path…each has a role, a gifting, a glory…You see this sort of thing at the center of every great story. Dorothy takes her journey with the Scarecrow, the Tin Woodman, the Lion, and of course, Toto. When he left Rivendell, Frodo didn’t head out with a thousand Elves. He had eight companions. When Captain John Miller is sent deep behind enemy lines to save Private Ryan, he goes in with a squad of eight rangers…[even] Jesus had the Twelve.
It is in our nature, our very design, to not go at it alone. This is why our art, our writings, and our history, so often remind us of this. Eldredge concludes:
Though we are part of a great company, we are meant to live in little platoons. The little companies we form must be small enough for each of the members to know one another as friends and allies. Is it possible for five thousand people who gather…to really and truly know one another? …how about five hundred? One hundred and eight? It can’t be done…It can be inspiring and encouraging to celebrate with a big ol’ crowd of people, but who will fight for your heart?
Our stories are reflections of who we are and remind us not to forsake our nature.
