"Give us this day our daily bread"
One of the mysteries of Scripture is that, through the Holy Spirit, passages say different things to different people at different times, perhaps determined by where that person is in his or her life at that time.
"Be still and know that I am God." (Psalm 46:10)
"Therefore I tell you, do not worry about your life, what you will eat or what you will drink, or about your body, what you will wear..." (Matthew 6:25)
"So do not worry about tomorrow, for tomorrow will bring worries of its own. Today's trouble is enough for today." (Matthew 6:34)
"Give us this day our daily bread" (Matthew 6:11) Or, in one translation, "Give us this day our bread for tomorrow."
All of these Scripture passages are teaching, advising, urging us to narrow our focus, simplify our lives, and simply trust God. Not ignore our future and our preparation for it; but, to ultimately come to realize that all of our tomorrows are in God's Hands and our calm, solid trust in Him today, each and every moment, is the assurance of our being prepared for all of the tomiorrows.
