"But Jesus said, “You feed them.”
“But we have only five loaves of bread and two fish,” they answered. “Or are you expecting us to go and buy enough food for this whole crowd?” For there were about 5,000 men there."
This was 5,000 men, not including women and children. The problem here is complex and not easily solved with money. To feed this multitude of people would cost 200 years worth of wages and all that was had was two fish and five loaves of bread. But when they shared all that they had, they still had extra to collect.
So if you care enough to ask as Jesus's disciples did, "Who will feed all these people?" You shouldn't be surprised to hear Jesus say, "You feed them." Jesus gives a very simple and practical solution to a very complex problem. So simple, in fact, that it seems he doesn't grasp the situation or is being inconsiderate and uncaring. But Jesus Christ is God and no one understands the situation better than He and still he says, "You feed them."
Jesus doesn't expect you to go out and spend your entire life savings feeding people. He knows you don't have that kind of money and one person alone cannot solve world hunger. However, as God has provided you with what little or what plenty you have, share it and God will make it enough.
