This already happen long time ago even before Jesus came. Moses and all Israel people walking in the desert without food and they feel very hungry, Moses pray to God Almighty and  the foods called Manna come down like rain. In this case what we have to do as a christian is to have faith, belief that whatever we ask in the name of Jesus Christ will be provide because God once say in the Bible something like this-I know what good for you just like a father know what is good for his son".
