30 The apostles returned to Jesus and told him all that they had done and taught. 31 And he said to them, “Come away by yourselves to a desolate place and rest a while.” For many were coming and going, and they had no leisure even to eat. 32 And they went away in the boat to a desolate place by themselves. 33 Now many saw them going and recognized them, and they ran there on foot from all the towns and got there ahead of them. 34 When he went ashore he saw a great crowd, and he had compassion on them, because they were like sheep without a shepherd. And he began to teach them many things. 35 And when it grew late, his disciples came to him and said, “This is a desolate place, and the hour is now late. 36 Send them away to go into the surrounding countryside and villages and buy themselves something to eat.” 37 But he answered them, “You give them something to eat.” And they said to him, “Shall we go and buy two hundred denarii[f]worth of bread and give it to them to eat?” 38 And he said to them, “How many loaves do you have? Go and see.” And when they had found out, they said, “Five, and two fish.”39 Then he commanded them all to sit down in groups on the green grass. 40 So they sat down in groups, by hundreds and by fifties. 41 And taking the five loaves and the two fish he looked up to heaven and said a blessing and broke the loaves and gave them to the disciples to set before the people. And he divided the two fish among them all. 42 And they all ate and were satisfied. 43 And they took up twelve baskets full of broken pieces and of the fish. 44 And those who ate the loaves were five thousand men.
So the the apostles go out on a short mission trip and see a lot of powerful results. When they return, Jesus tells them they need to get away and recharge their batteries. The problem is: momentum. It was not really a problem, but the thing that every spiritual endeavor hopes will result. Momentum happens when people are excited about what God is doing and faith is growing. The Spirit of God is clearly moving. People are praying and believing that God will answer. This is the spiritual mountain top.
In spite of the need for some rest, a crowd gathers, and Jesus begins to teach them. When it is time for dinner, the apostles think they should just send the people away hungry, but Jesus does not send people away hungry; He feeds them. Jesus is not bound by circumstances, so He takes what seems to be inadequate and meets the need. The point is that our part is to offer Jesus what we have; Jesus will do the rest.
