A soul depends on grace in proportion to its desire for greater perfection. God’s help is necessary at every moment because without it the soul can do nothing.
The world, nature, and the devil together wage war so fiercely and so relentlessly that, without this special help and this humble, necessary dependence, they would carry off the soul against its will.
This seems contrary to nature, but grace finds pleasure and peace therein.
