The miracle stories in the Gospels (like the ones in the OT) are stories with the wow factor that’s part of all miracle stories – think of the ones we hear on the infomercials on TV 😉
They called this reading “Feeding the Five Thousand” but it comes in a context. Luke (like the other gospels (except Thomas which the early Christians excluded from the Bible) does not tell an unconnected series of “stories about Jesus” rather he tells us “The Story of Jesus”.
The context in which this miracle is told to us shows us that this miracle is part of a process showing us Jesus bringing to life aspects of what the OT tells us to hope for when the Messiah comes. But then Jesus tells us that he’s a different sort of Messiah, not a glorious but a suffering one. Before God puts the cap on it all showing that this suffering Messiah is indeed glorious!
