Chapter 38 — Part IV: Prayer — The Fourth Petition: Give Us This Day Our Daily Bread
Section 34. "This Day" — The words this day remind us of our common infirmity. For who is there that, although he does not expect to be able by his own individual exertions to provide for his maintenance during a considerable time does not feel confident of having it in his power to procure necessary food for the day? Yet even this confidence God will not permit us to entertain, but has commanded us to ask Him for the food even of each successive day; and the necessary reason is, that as we all stand in need of daily bread, each should also make daily use of the Lord's Prayer.
