336. As for the ways divine providence works with its means, and uses them to form us and bring us toward perfection, they are infinite in number and infinite in variety as well. There are as many of them as there are actions of divine wisdom, prompted by divine love, for our salvation; as many therefore as there are things that divine providence does in keeping with its laws, as already discussed.
I have already shown [164, 180, 296] that these ways are deeply hidden by comparing them with the way our souls work within our bodies, ways we know little or almost nothing about--how our eyes, ears, nostrils, tongue, and skin register sensations, for example, how our stomach digests, our mesentery produces chyle, our liver works on our blood, our pancreas and spleen purify it, our kidneys separate it from contaminating fluids, our heart gathers it in and sends it out, our lungs cleanse it, and our brain refines it and gives it new life, along with countless other processes, all subtle, whose depths our science can scarcely plumb.
We can see from this that we are even less able to plumb the depths of the subtle workings of divine providence. It is enough that we know its laws.
