You can see all the lectionary readings for Proper 13, Year B by clicking here. I have chosen to discuss the passage from the Gospel of John.
After Jesus feeds the five thousand, he leaves the people behind. Then the people go looking for him and find him on the other side of the lake. He asks why they are looking for him–if it is only because they saw miraculous signs. He tells them they liked that he fed them, but earthly food doesn’t last long. He tells them to work for the food that gives them eternal life. “The Son of Man will give you that food. He is the only one qualified by God the Father to give it to you.”
So the people ask what God wants of them and he tells them to believe in the one God sent. Then they ask for more miracles and talk about the manna God sent the Israelites in the desert.
Again, they seem focused on miracles but also mostly on physical food. As I said about last week’s passage, Jesus does care about their physical well-being, but he also cares about their souls.
I can assure you that Moses was not the one who gave your people bread from heaven. But my Father gives you the true bread from heaven. God’s bread is the one who comes down from heaven and gives life to the world.
John 6:32-33 (Easy-to-Read Version)
So the people say, “Sir, from now on give us bread like that.” I think they still probably don’t get it.
Jesus responds that he is the bread that gives life, and those who come to him will never be hungry or thirsty. This, again, seems to be about spiritual hunger and thirst, rather than physical. And again, this passage forecasts our Eucharist, when we receive physical bread but also the spiritual bread of Christ and his grace.
