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.

72. However, since not many people know that this law can be a law of divine providence (primarily because in spite of the fact that divine providence is constantly leading us to think and intend what is good and true, we have a freedom to consider what is evil and false), I need to proceed clearly, step by step, so that this will be grasped. The sequence will be as follows:

1. We have a capacity for disciplined thought and a certain latitude, or rationality and freedom, and these two abilities are in us as gifts from the Lord.

2. Whatever we do from our freedom, whether we have thought it through rationally or not, seems to be ours as long as it is in accord with our reason.

3. Whatever we have done from our freedom in accord with our thinking becomes a permanent part of us.

4. It is by means of these two abilities that the Lord reforms and regenerates us; without them we could not be reformed and regenerated.

5. We can be reformed and regenerated by means of these two abilities to the extent that we are brought to a realization that anything good and true that we think and do comes from the Lord and not from us.

6. The Lord's union with us and our responsive union with the Lord comes about by means of these two abilities.

7. Through the whole course of his divine providence, the Lord protects these two abilities untouched within us, as though they were sacred.

8. This is why it is integral to divine providence that we act from freedom, and in accord with reason.
