By golly, you've finally got it. To become perfect.
So it's a question of timing?
If God acts on you after you are born, in a completely gratuitous way to rescue you from sin, that does not make you divine, though you are a human whose soul is made perfect.
On the other hand, if God acts on Mary before she is born, in a completely gratuitous way to resuce her from sin, that makes her divine?
