240. There are two abilities within us, gifts from the Lord, that distinguish us from animals. One ability is that we can discern what is true and what is good. This ability is called "rationality," and is an ability of our discernment. The other ability is that we can do what is true and what is good. This ability is called "freedom," and is an ability of our volition. Because of our rationality, we can think what we want to think, either in favor of God or against God, in favor of our neighbor or against our neighbor. We can also intend and do what we are thinking, or when we see something evil and are afraid of the penalty, can use our freedom to refrain from doing it. It is because of these two abilities that we are human and are distinguished from animals.

These two abilities are gifts from the Lord within us. They come from him constantly and are never taken away, for if they were taken away, that would be the end of our humanity. The Lord lives in each of us, in the good and the evil alike, in these two abilities. They are the Lord's dwelling in the human race, which is why everyone, whether good or evil, lives forever. However, the Lord's dwelling within us is more intimate as we use these abilities to open the higher levels. By opening them, we come into consciousness of higher levels of love and wisdom and so come closer to the Lord. It makes sense, then, that as these levels are opened, we are in the Lord and the Lord is in us.
