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.

169. Throughout the created universe, both in its grandest constituents and in its most infinitesimal, we find these three ingredients, namely, end, cause and effect. These three are found in the grandest and most infinitesimal constituents of the universe for the reason that the same three exist in God the Creator, who is the Lord from eternity. However, because He is infinite, and because the infinite elements in an infinite being are, in a distinct combination, one (as demonstrated above in nos. 17-22), therefore in Him these three also, and the three in His infinite elements, are, in a distinct combination, one.

It is in consequence of this that the universe - which was created from His being, and which regarded in terms of its functions is an image of Him - acquired these three ingredients in each and all of its constituents.
