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.

3303. 'And after this his brother came out' means truth. This is clear from the meaning of 'brother' as good, and also as truth, for the two are called brothers. Charity is the brother of faith, or good the brother of truth, see 367, so that conversely faith is the brother of charity, or truth the brother of good. Also within the natural, the affection for good is called a brother and the affection for truth a sister, 3160, as well as husband and wife (mulier), and man and wife (mulier). But these are always used with respect to the states that are being described.
