As the people of Israel are freed from the slavery of Egypt, they have one response: complaining. They're hungry, they're thirsty. Sounds much like the children in our lives who are constantly hungry and thirsty even after they've just been fed. How does God respond to hunger and thirst? He meets our needs. He gives us food and drink, just like He did with the Israelites. God doesn't want us to just be physically nourished, He wants us to be spiritually fed, and so Jesus comes to us as the bread from heaven, the bread of life, and gives us exactly what we need.
