42. It is the same with love and wisdom, the only difference being that the substances and forms that are love and wisdom are not visible to our eyes as are the organs of our external senses. Still, no one can deny that those matters of love and wisdom that we call thoughts, perceptions, and feelings are substances and forms. They are not things that go floating out from nothing, remote from any functional and real substance and form that are their subjects. There are in fact countless substances and forms in the brain that serve as the homes of all the inner sensation that involves our discernment and volition.

What has just been said about our external senses points to the conclusion that all our feelings, perceptions, and thoughts in those substances and forms are not something they breathe out; they themselves are functional and substantial subjects. They do not emit anything, but simply undergo changes in response to the things that touch and affect them. There will be more later [210, 273] on these things that touch and affect them.

522. First, though, let me state what divine mercy is. Divine mercy is a pure mercy toward the whole human race with the intent of saving it, and it is constant toward every individual, never withdrawing from anyone. This means that everyone who can be saved is saved. However, no one can be saved except by divine means, the means revealed by the Lord in the Word. Divine means are what we refer to as divine truths. They teach how we are to live in order to be saved. The Lord uses them to lead us to heaven and to instill heaven's life into us. The Lord does this for everyone; but he cannot instill heaven's life into anyone who does not refrain from evil, since evil bars the way. So to the extent that we do refrain from evil, the Lord in his divine mercy leads us by divine means, from infancy to the end of life in the world and thereafter to eternity. This is the divine mercy that I mean. We can therefore see that the Lord's mercy is pure mercy, but not unmediated: that is, it does not save people whenever it feels like it, no matter how they have lived.
