Dr. Luther’s Small Catechism lesson for the week of March 15, 2015:
[III] THE LORD’S PRAYER
IN THE PLAIN FORM IN WHICH THE HEAD OF THE FAMILY
SHALL TEACH IT TO HIS HOUSEHOLD
THE FOURTH PETITION
“Give us this day our daily bread.”
What does this mean?
Answer: To be sure, God provides daily bread, even to the wicked, without our prayer, but we pray in this petition that God may make us aware of his gifts and enable us to receive our daily bread with thanksgiving.
What is meant by daily bread?
Answer: Everything required to satisfy our bodily needs, such as food and clothing, house and home, fields and flocks, money and property; a pious spouse and good children, trustworthy servants, godly and faithful rulers, good government; seasonable weather, peace and health, order and honor; true friends, faithful neighbors, and the like.
