These are some comments written by Dr. Martin Luther concerning this portion of the Lord’s prayer. I found his writing on “What is Meant by Daily Bread?” to be rather enlightening.
GIVE US THIS DAY OUR DAILY BREAD.
What does this mean?
God certainly gives daily bread to everyone without our prayers, even to all evil people, but we pray in this petition that God would lead us to realize this and to receive our daily bread with thanksgiving.
What is meant by daily bread?
Daily bread includes everything that has to do with the support and needs of the body, such as food, drink, clothing, shoes, house, home, land, animals, money, goods, a devout husband or wife, devout children, devout workers, devout and faithful rulers, good government, good weather, peace, health, self-control, good reputation, good friends, faithful neighbors, and the like.
