Generally speaking, people who are at lower levels of an organization serve those at higher levels. Bosses boss and their employees serve; coaches devise strategy and players do what the coach tells them to do; engineers design car parts and workers assemble them according to the engineers' instructions. Ideally, of course, it's a two-way street: A good boss knows he is really there to help his employees succeed; a good coach creates strategies based on his players' strengths. Even there, though, the boss and coach are really working in service of a higher goal, seeking organizational success. The same is true in the spiritual sense of the Bible. When someone serves another, they are in a lower state, serving a higher state (or a deeper evil, if they are being enslaved by people who represent evil). This can take many different forms, depending on the circumstances. In many cases, this creates a connection between "service" and intellectual things. This is because who we are is determined by what we love; our loves are the deepest part of us. What we think, our reasoning and intellect and the things we learn about, come from those loves and serve those loves.

9419. 'And Moses rose up, and Joshua his minister' means the Word and its representative. This is clear from the representation of 'Moses' as the intermediary between the Lord and the people who are restricted to the outward sense of the Word, separated from the inward, thus also as the Word, as accords with what has already been shown just above in 9414; and from the representation of 'Joshua his minister' as its representative. The reason why 'Joshua' here means that representative is that what is representative serves and ministers, in order that the outward things of the Word and of worship may present themselves to the Lord through the intermediary, who was Moses. But these are matters such as are scarcely intelligible except to those who know about the ways in which a representation of the outward or literal sense of the Word is accomplished in heaven. That is to say, it is represented in one way with those who are acquainted with the outward sense of the Word and at the same time with the inward, that is, those who are acquainted with the outward sense of the Word and at the same time with true teachings of the Church, and in another way with those restricted to the outward sense, separated from the inward, as with this people. How it was accomplished with this people, see 4311.

[2] Some idea may be formed from this regarding the intermediary that 'Moses' represents and the ministering representative that 'Joshua' represents. That is to say, there is an inward holiness which Divine Truth emanating from the Lord possesses, thus which the Word and worship springing from it possess. This flows into heaven and is received there by angels. There is also an inflow of holiness indirectly through that inward holiness, as well as directly from the Lord, to good spirits present with a person engaged in reading the Word or in worship springing from it. This holiness is called an outward holiness, and when it flows in with a person it produces representative images formed in accord with the correspondences known to the person. All this helps one to see what use the intermediary serves, which Moses represents now, and what use the minister serves, which Joshua represents, namely that the outward holiness acts as intermediary, while the representative existing on the lowest level of order acts as minister. But it should be recognized that the idea of Divine Truth flowing in is unintelligible to a person unless the Lord sheds light on the idea. For the person sees what happens in no other way than this, that the holiness of the Word and the holiness of worship flows from the person to the Lord. But this order is inverted order, and is called physical influx, which is an appearance and not at all the reality; see what has been shown in the places referred to in 9223, 9227 (end).
