He says we can pray, “Give us each day our daily bread.” We can ask him for provision.
Obviously, when Jesus talks about daily bread, he’s talking about the basic necessities of life.
It’s interesting that the word translated “daily” or “each day” is a word that is used in the Bible only in connection with the Lord’s Prayer. It is not used outside the Scriptures, in classical Greek literature. The word was a mystery, and translators guessed at it, and usually guessed right. But several years ago on a piece of papyri they found a woman’s grocery list out of the ancient world. On that list there were several things that were perishable. And next to each item she had epiousios—enough for the day.
In our culture, where we have freezers full of food, we hardly take this seriously, but in most of the world, it’s a basic request. If we pray this prayer, we are asking God to provide our needs as we serve his kingdom. We are acknowledging that for our bread, our threads, the things we need, we will turn to God, and he will supply.
