Creation has its own goodness and proper perfection, but it did not spring forth complete from the hands of the Creator. the universe was created “in a state of journeying” (in statu viae) toward an ultimate perfection yet to be attained, to which God has destined it. We call “divine providence” the dispositions by which God guides his creation toward this perfection:
By his providence God protects and governs all things which he has made, “reaching mightily from one end of the earth to the other, and ordering all things well”. For “all are open and laid bare to his eyes”, even those things which are yet to come into existence through the free action of creatures.
The witness of Scripture is unanimous that the solicitude of divine providence is concrete and immediate; God cares for all, from the least things to the great events of the world and its history. the sacred books powerfully affirm God’s absolute sovereignty over the course of events: “Our God is in the heavens; he does whatever he pleases.” and so it is with Christ, “who opens and no one shall shut, who shuts and no one opens”. As the book of Proverbs states: “Many are the plans in the mind of a man, but it is the purpose of the LORD that will be established.”
And so we see the Holy Spirit, the principal author of Sacred Scripture, often attributing actions to God without mentioning any secondary causes. This is not a “primitive mode of speech”, but a profound way of recalling God’s primacy and absolute Lordship over history and the world, and so of educating his people to trust in him. the prayer of the Psalms is the great school of this trust.
Jesus asks for childlike abandonment to the providence of our heavenly Father who takes care of his children’s smallest needs: “Therefore do not be anxious, saying, “What shall we eat?” or “What shall we drink?”. . . Your heavenly Father knows that you need them all. But seek first his kingdom and his righteousness, and all these things shall be yours as well.”
