Note 33 at Mt 6:11: Notice that Jesus didn't instruct us to pray for a year's supply of bread. The Jews, whom God miraculously sustained for forty years in the wilderness by giving them angels' food (Ps 78:24-25) to eat, had to gather the manna every day. They could not gather more than one day's supply at a time (except before the Sabbath) or it would rot (Ex 16:19-21). Ex 16:4 says that the Lord gave them their bread daily to "prove them, whether they will walk in my law, or no." The Lord desires for the just to live by faith (Ga 3:11); that is, to make it a lifestyle, not just a once-in-a-while occurrence.
