Before the movie Finding Dory, there was a charming Disney Pixar Short called Piper (trailer above). A mother sandpiper is encouraging her little piper baby to learn how to forage food for herself. Sandpipers go down to the ocean and when the wave is out, they search for little clams. Bubbles indicate where some of them are, so the sandpipers look for those bubbles and quickly dig and eat before the wave returns. The young sandpiper isn't so sure about having to forage for herself. She wishes her mama would still just feed her, but with some encouragement she tries. It all goes south when a wave completely soaks her. Eventually though, she meets a family of little crabs, and the child in that family teaches the piper a different technique than the sandpipers use: the crabs burrow a little down into the sand, so the wave can't knock them off their feet. Then they are able to see underwater for a brief moment the great abundance of food that the wave has exposed and will be re-covered as soon as the wave recedes. There is so much more food available than the standard piper technique of looking for bubbles identifies. The piper is no longer afraid of the water and is able to harvest the bounty for herself and others using this improved technique.
A written description does not do the story justice; I highly recommend take six minutes to watch it (https://itun.es/us/HFKUeb). Piper has all of the classic Pixar elements: stunning animation, perfect music and sound effects, and a focus on challenge, fear, courage, and growth. I think it is also a metaphor for the kingdom of God.
The kingdom of God is like a sandpiper who is deathly afraid of the ocean and unable to collect the meager harvest, until the day she meets a crab who teaches her how to brace herself in the sand and see the riches that the ocean holds, producing food that was thirty fold, sixty fold, even one hundred fold the average, enough to share with her family and sandpiper neighbors.
Jesus teaches us that the kingdom of God is already among us and within us. We need to learn how to see it. We need to open our eyes. Just like that little sandpiper, we can brace ourselves in the sand and open our eyes when the waves of life roll over us, so that we can see the abundance of God's grace in the midst of all of the difficulty. God's grace is sufficient to nourish us as we face any challenge.
