There are really two meanings for "build" in the Bible. When something is being built for the first time, or built in the most typical sense, it means collecting relatively external ideas to build up a doctrinal system. In other cases, though, "build" is used in reference to something that has been destroyed. In such cases, "build" refers to removing our desires for evil so we can began a new stage of spiritual growth. In these cases "build" is often used together with "raise up," which means removing false ways of thinking in the same process.

6667. 'With rigour' means without showing any mercy. This becomes clear without explanation, for those spoken of immediately above in 6666 have no mercy because they have no love of the neighbour, only self-love. Love of the neighbour which seems to be present among them is nothing else than self-love. For as long as another is favourably disposed towards them, that is, is on their side, they love him; but as long as he is not favourably disposed towards them or not on their side they reject him, and if previously their friend they hate him. Attitudes such as this lie concealed in self-love, though they do not reveal themselves in the world, only in the next life, where they burst out into the open. The reason why they burst out there is that there outward appearances are taken away; and when they are taken away, one sees what a person has been like inwardly.
