So the apostles come back, thrilled with all they have accomplished, and they're withdrawn to tell Jesus all the news. The crowds tag along, and when the apostles encourage Jesus to send them away to the nearby villages for foods, Jesus challenges them to feed the crowds. Remember -- Jesus sent them away and told them to take nothing, so they're not resource-rich, and now Jesus has challenged them with what seems like an impossible task. The high they have from their achievements must have ended quickly.
Jesus is always challenging us to grow. Even on the back of huge achievements, Jesus is looking at what comes next for us. If we get comfortable, Jesus reminds us that our purpose is to constantly grow closer to Christ. It's not because he doesn't love us, but because he wants to challenge us to always draw our hearts closer to God and closer to a life of service to one another. Jesus sees so many needs -- these crowds are hungry, and he uses the church to serve and to show the love of God.
