4803. A matter wholly unknown in the world and worthy of mention is this: The states in which good spirits and angels live undergo constant change and perfection. In this way they are conveyed to the more internal parts of the province in which they dwell, and so into more excellent functions. For in heaven purification takes place constantly, which is so to speak a new creation. Yet the situation is that no angel to all eternity can possibly attain complete perfection. The Lord alone is the perfect One, He being the root and the source of all perfection. Those who correspond to the mouth constantly wish to be speaking, for speaking gives them utmost pleasure. While undergoing perfection they are restricted to speaking nothing but that which is beneficial to companions, the community, heaven, and the Lord. The delight they take in speaking in that way grows in the measure that the desire to regard themselves in what they speak and to strive after wisdom from what is properly their own passes away from them.

9517. 'The faces of the cherubs shall be towards the mercy-seat' means the interiors looking unceasingly towards good, thus towards the Lord. This is clear from the meaning of 'the mercy-seat' as the good of love, from which comes the hearing and reception of all things that belong to worship, dealt with above in 9506, thus also as the Lord since all the good of love originates in the Lord and is the Lord Himself as He resides with angel and man; from the meaning of 'the faces' as the interiors, dealt with immediately above in 9516; and from the meaning of 'the cherubs' as watchfulness and providence, guarding against access to the Lord except through the good of love, dealt with in 9509.

[2] What happens is this: Heaven and the Church, or the angels of heaven and members of the Church, receive protection from the Lord by having their interiors raised towards Him; and when they are raised they are suffused with the good of love to Him and the good of love towards the neighbour. This is what being raised towards the Lord is; and in this way, as has been stated, angels in heaven and members of the Church receive protection. Those who are raised by the Lord turn their face constantly towards the Lord, because the Lord keeps them joined to Himself through the good of love, whereas those who are not raised turn their face away from the Lord. All this shows what is meant by the requirement that the faces of the cherubs should be 'towards the mercy-seat'. But regarding that turning of themselves towards the Lord something will in the Lord's Divine mercy be stated from experience elsewhere.

9007. 'Anyone striking a man - and he dies' means injury done to the truth of faith, and consequent loss of spiritual life. This is clear from the meaning of 'striking' as injuring by means of falsity, dealt with in 7136, 7146; from the meaning of 'a man' as the truth of faith, dealt with below; and from the meaning of 'dying' as loss of spiritual life, dealt with in 5407, 6119, 7494, no other kind of life being meant in the internal sense, though natural life is meant in the external sense. The reason why injury done to the truth of faith leads to the destruction of spiritual life is that good united to truth composes that life, and therefore when truth is snatched away good falls to the ground, and so does spiritual life.

[2] The reason why 'a man' means the truth of faith is that in heaven they do not focus their attention on the person or anything of the person, only on things in the abstract, that is, without envisaging any actual person, 4380 (end), 8343, 8985. Consequently they do not think of 'a man' when this expression is used in the Word, for a man is a person; instead they think of his power of mind which makes him a man, namely the power of understanding. And when they think of this they think of the truth of faith, since it belongs to that power of mind and not only enlightens it but also shapes it. Just as in heaven they think of someone's power of understanding when 'a man' (vir) is used, so they think of his power of will when 'a human being' (homo) is used; for a human being is a human being by virtue of the will, whereas 'a man' is such by virtue of the understanding. And as the will is really the human being, 'human being' therefore means the good of love, since it belongs to the will, perfecting and composing it. For the meaning of 'a man' as the power of understanding and consequently the truth of faith, see 158, 265, 749, 1007, 2517, 3134, 3309, 3459, 4823, 7716; and for 'a human being' as the good of love, 768, 4287, 7523, 8547, 8988.
