But along the lines of saint Paul's declaration, "
it is [God] who gives everything -- including life and breath -- to everyone. ... it is in him that we live, and move, and exist, as indeed some of your own writers have said: We are all his children. "
There is in Paul's declaration a surprising element of a pre-existing relationship between God and humanity.
One that gets scant attention at times.
We are, by nature, God's children. And sin makes us run & hide from God, as did Adam and Eve, "
[Adam and Eve] heard the sound of Yahweh God walking in the garden in the cool of the day, and they hid from Yahweh God among the trees of the garden"
Even in their fallen state they acted with freedom, but their fall made them fearful of their Father.
That is the tragedy of sin. Other tragic elements also exist.
So how did God dress their wound? [puns intended

]
I presume, as you would expect, that they were not yet dead, that their death would take time and would not become irrevocable until their life on Earth ran its course.
Yahweh God made tunics of skins for the man and his wife and clothed them.
The above is a little symbolic I reckon, covering their nudity with animal skins seems like a reference to sacrificial animals that would come into the story later (with Cain & Able then with Noah and then with Abraham and Moses and Israel and finally with Jesus Christ).
There's always grace in their lives as long as they live (on Earth).
There's always freedom as long as they are alive.
Freedom to choose and freedom to refuse.
And there's always mystery in grace.
God reveals it, but he does not always explain every detail.
So the mystery is both in the fact of revealing and in the absence of detailed explanation.
It is not until Jesus comes that detailed explanation arrives.
But it arrives as a person not as scripture.
So, Catholic theology is happy to admit mystery (in the sense of revealed truth that does not contain - in scripture - all the details and hence is a little bit misty (pun intended)).
Freedom is our birth right. It is included in the deal. It is part of our created nature.
Responsibility is predicated on freedom.
If we acted without freedom - by instinct, for example - then we would be blameless. Just as other creatures are blameless when acting without freedom.
Hmmm .. maybe I ought to stop. I am writing way more than I intended.
God bless.
