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.

8897. 'Honour your father and your mother' means love for goodness and truth, in the highest sense for the Lord and His kingdom. This is clear from the meaning of 'honouring' as loving, for in the spiritual sense 'honour' is love, because in heaven one loves another, and in loving him also honours him since love is present within honour (honour without love there is rejected, indeed spurned, because it is devoid of life from good); from the meaning of 'father' as goodness, dealt with in 3703, 5581, 5902, 6050, 7833, 7834, and in the highest sense as the Lord in respect of Divine Goodness, 15, 1729, 2005, 2803, 3704, 7499, 8328 (the reason why 'Father' in the highest sense is the Lord is that He imparts new life to the person, so that this life may make that person a son and heir of His kingdom); and from the meaning of 'mother' as truth, dealt with in 3703, 5581, and in the highest sense the Lord in respect of Divine Truth, thus His kingdom since Divine Truth which emanates from the Lord makes heaven. The reason why the Lord's Divine Truth makes heaven is that in the next life the Lord in respect of Divine Good is the Sun, and in respect of Divine Truth is the Light. This Divine Light radiating from the Lord as the Sun is what enlightens angelic minds and fills them with intelligence and wisdom, causing them to be angels of light. Divine Good is present within Divine Truth, even as heat from the sun is present within the light in springtime and summer in the world.
