A "house" is essentially a container -- for a person, a family, several families or even a large group with shared interests (think of the term "houses of worship.") In the Bible, a "house" is also a container, but for spiritual things rather than natural things. In various uses a "house" can represent part of the mind, the whole mind, a whole person or even a church. The other nuance to the word "house" is that it is generally used in regards to our affections and desires rather than our thoughts and principles. This makes sense; we tend to engage our thoughts and rationality when we are out in the world doing our work, but when we are inside our houses we are driven most by love for our families and the desire to be good to those we love. So "house" tends to represent the things we want and care about -- which are ultimately the things that define us.

8327. 'On the mountain of Your inheritance' means the heaven where the good of charity resides. This is clear from the meaning of 'mountain of inheritance' as heaven. For 'mountain' means the good of love, 795, 796, 2722, 4210, 6435, and 'inheritance' means another's life, in this instance the Lord's; thus the life of goodness and truth which is derived from the Lord is meant, since those who possess this life are heirs of the kingdom and are called sons, 2658, 2851, 3672, 7212. Since these things are meant by 'the mountain of inheritance', heaven is also meant; for heaven is heaven by virtue of the good of love and it is the inheritance belonging to those who are the Lord's.
