In the second half of Exodus, we begin to learn that although God has gotten His people out of slavery in Egypt, He still has to get the slavery out of them. There is still much that holds them in their old way of life, and where this shows up is in the wilderness when the people find themselves running short of food and water. Though they have been freed from Pharaoh, their selfish hearts lead them to complain against God and want to return to Egypt. But in the face of their complaints, God responds with gracious provision. In these encounters, we learn some important things about God Himself. We learn about the process of God, the provision of God, and the patience of God.
