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.

The Bible describes many things as being holy, or sacred. The Ark of the Covenant is one very holy object. The inmost chamber of the tabernacle is called the "Holy of Holies". Things that proceed from the Lord are holy. Objects are holy if they contain something, or represent something, from the Lord. For that reason, the names of the Lord in human languages are holy because they represent qualities of the Lord, things that are Him. The Bible is holy because it contains, interiorly, the Lord's divine truth. The tabernacle of Israel was holy -- not because of the wood or gold or dyed cloth -- but because those things represented qualities that the Lord has. Those same qualities exist, as in an image, in the spiritual states of people who follow the Lord's laws. No person is holy, but if a person's mind contains truth from the Lord and his or her will comes to love the truths and the actions that these truths suggest to him, then his or her mind will contain holy things, because those truths and loves come from the Lord. These things become that person's life and they remain with that person in heaven, after death.
