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.

4809. When the Son of Man comes in His glory means when Divine Truth will be visible in its own light, as happens to everyone when he dies; for at that time he comes into the light of heaven, in which light he is able to perceive what is true and good, and from this the nature of it. 'The Son of Man' in the internal sense of the Word is the Lord as regards Divine Truth, and so it is Divine Truth which comes from the Lord; 'glory' is intelligence and wisdom that flow from this, which is seen as light, and by angels as brilliant light. This brilliant light that holds within it wisdom and intelligence flowing from Divine Truth that comes from the Lord is that which in the Word is called 'the glory'. As regards 'the Son of Man' in the internal sense meaning Divine Truth, see 2159, 2803, 2813, 3704.

[2] And an the holy angels with Him means the angelic heaven. 'The holy angels' in the internal sense are truths which come from the Lord's Divine Good, for in the Word the expression 'angels' is not used to mean angels but things that are from the Lord, see 1925, 4085. Angels are recipients of the life of truth proceeding from the Lord's Divine Good; and in the measure they receive it they are angels. From this it is evident that 'angels' means those truths. Because the subject here is the state of each person after death, and the judgement of each one according to what his life is, it is said that all the holy angels will be with Him, meaning that the judgement will be effected through heaven; for every influx of Divine Truth takes places through heaven. No one can receive a direct influx.

[3] Then He will sit on the throne of His glory means the judgement, for 'throne' is used to refer to the Lord's kingship, and the Lord's kingship is Divine Truth, 1728, 2015, 3009, 3670, Divine Truth being the starting-point and the standard of that judgement.

[4] And before Him all nations will be gathered means that every good and every evil of everyone will be disclosed - for 'nations' in the internal sense of the Word means forms of good, and in the contrary sense forms of evil, 1259, 1260, 1416, 2588 (end), 4574. Thus it is the showing up in Divine light - that is, in light flowing from Divine Truth - of every good and every evil that is meant by 'before Him all nations will be gathered'.

[5] And He will separate them one from another as a shepherd separates the sheep from the goats means the separation of good from evil, for 'the sheep' are those in whom good is present, and 'the goats' those in whom evil is present. Strictly speaking the expression 'the sheep' is used to describe those in whom charity, and faith derived from charity, are present, 'the goats' to describe those in whom faith but no charity is present. Both these types of people are referred to here. As regards 'the sheep' meaning those in whom charity and faith derived from it are present, see 2088, 4169, and 'the goats' those in whom faith but no charity is present, 4769.

[6] And He will place the sheep at His right hand and the goats at the left means a separation into truths derived from good, and falsities derived from evil. Those governed by truths derived from good are also visibly present in the next life on the right, while those governed by falsities are on the left. Consequently being stationed on the right hand and on the left implies an ordering in which life is the determining factor.
