Can you quote pertinent passages from this patristic opus for us?
Read chapters 25-30 for an exact exposition.
From chapter 29: "Providence, then, is the care that God takes over existing things. And again: Providence is the will of God through which all existing things receive their fitting issue. But if Providence is God's will, according to true reasoning all things that come into being through Providence must necessarily be both most fair and most excellent, and such that they cannot be surpassed. For the same person must of necessity be creator of and provider for what exists: for it is not meet nor fitting that the creator of what exists and the provider should be separate persons. For in that case they would both assuredly be deficient, the one in creating, the other in providing. God therefore is both Creator and Provider, and His creative and preserving and providing power is simply His goodwill. For whatsoever the Lord pleased that did He in heaven and in earth, and no one resisted His will. He willed that all things should be and they were. He wills the universe to be framed and it is framed, and all that He wills comes to pass.
...Moreover, it is to be observed that the choice of what is to be done is in our own hands: but the final issue depends, in the one case when our actions are good, on the cooperation of God..."
Perhaps then what was being asked is the relationship of God's absolute (total) sovereignty and our free will? If so, St. John also answers this question. St. John was not loquacious
I am dubious that we actually need any greater definition of God's Providence than given by the very exegesis of God Himself, but I understand that many converts are impatient and desire to crash course or cliff note the work of the Holy Spirit who will Himself instruct them through attentive attendance in Vigil, Liturgy and all other services of the Church. I also understand as described by the blessed Augustine explained, heretics read the Scriptures through blinking eyes and thus their expositions of what they see is men walking as trees.
Did the Theotokos need a Patristic commentary to understand Providence?
The understanding of what Providence is springs up from within the submissive heart where it abides as a seed until the circumstances appear to make manifest God's love. Nothing and no one is outside of God's Providence, but we may certainly oppose, resist and work against His Providence which is the manifestation of His love. Even animals experience the Providence of God according to the order, rank or choir of creation in which they abide and as our Lord expounded.
