281. 4. So the permission of evil is for the purpose of salvation. We know that we are quite free in our thinking and intentions, but are not free to say and do whatever we think and intend. We can be atheists in our thoughts, denying the existence of God and blaspheming the holy contents of the church's Word; we can even want to destroy them utterly by what we say and do; but civil and moral and ecclesiastical laws hold us back. So we indulge in these ungodly and criminal practices in our thoughts and our wishes and even in our intentions, but still not in our actions. People who are not atheists are still quite free to harbor any number of evil thoughts, thoughts about cheating, lust, vengeance, and other senseless things, and even act them out at times.

Is it credible that if we did not have this complete freedom we would not only be beyond salvation but would completely perish?

[2] Listen to the reason. We are all immersed in many kinds of evil from birth. They are in our volition, and we love whatever is in our volition. That is, we love all the intentions that come from within; and we intend whatever we love. This love of our volition flows into our discernment and makes itself felt there as pleasure. It moves from there into our thoughts and into our conscious intentions. So if we were not allowed to think the way the love of our volition wants us to, the love that is within us by heredity, that love would stay closed in and never come out where we could see it. Any such hidden love for evil is like an enemy plotting against us, like pus in a sore, like a toxin in the blood, and like an infection in the chest. If they are kept hidden, they hasten us to our end.

On the other hand, when we are allowed to think about the evils of our life's love even to the point of wanting to act them out, they are healed by spiritual means the way a life-threatening illness is cured by physical means.

[3] I need to explain what we would be like if we were not allowed to think in keeping with the pleasures of our life's love. We would no longer be human. We would have lost the two abilities called freedom and rationality that are the essence of our humanity. The pleasures of those loves would take control of the inner reaches of our minds so completely that the door would be opened wide. We then would not be able to avoid talking and acting in similar fashion, displaying our madness not only to ourselves but to the whole world. Eventually we would not know enough to cover our private parts. It is to keep this from happening that we are allowed to think about and to intend the evils we have inherited, but not to utter and do them. In the meanwhile, we learn civic, moral, and spiritual principles that also work their way into our thinking and displace these insane principles. The Lord heals us by this means, though only to the extent that we know how to guard the door, and not unless we believe in God and ask for his help to resist our evils. Then to the extent that we resist them, he does not let them into our intentions, and eventually not into our thoughts.

[4] We do therefore have a freedom to think as we wish, in order that our life's love may come out of hiding into the light of our discernment; otherwise we would have no knowledge of our evil and could not abstain from it. It would then follow that the evil would gain strength within us to the point that there was no space for recovery within us and, since the evil of parents is passed on to their progeny, hardly any space for recovery in any children we might beget. The Lord makes sure, however, that this does not happen.
