3721. 'And this is the gate of heavens means that which serves as the ultimate degree of order, through which there is, so to speak, a way in from the natural creation. This is clear from the meaning of 'the gate' as that through which exit or entrance is made. The reason why here that which serves as the ultimate degree of order is meant is that the subject is the natural, which 'Jacob' represents. What 'a gate' means is clear from what has been stated and shown in 2851, 3187, and the fact that the natural is the ultimate degree of order from what has been introduced in 775, 2181, 2987-3002, 3020, 3147, 3167, 3483, 3489, 3513, 3570, 3576, 3671. The reason why through that ultimate degree there is so to speak a way in from the natural creation is that man's natural mind is the place through which things of heaven, that is, which are the Lord's, flow in and come down into the natural creation; and through that same mind the things that belong to the natural creation go back up, see 3702. The fact that there is so to speak an entrance from the natural creation through the natural mind into interior parts may be seen from what has been stated and shown in various places before.

[2] It seems to man as though worldly objects enter in through his physical or external senses and affect interior things, and so that there is an entrance from the ultimate degree of order into things that are within. But this is an appearance and illusion, as is evident from the general rule that what is secondary cannot flow into what is primary, or what amounts to the same, what is lower cannot flow into what is higher, or what is also the same, what is exterior into what is interior, or what is still the same, things of the world and the natural creation into those of heaven and of the spirit. For the former are grosser, the latter purer, and the grosser things that belong to the external or natural man come into being and are kept in being from those belonging to the internal or rational man. Those grosser things are unable to have any effect on the purer things but are affected by them. The nature of this influx however, seeing that appearance and illusion itself convince people that the reverse is true, will in the Lord's Divine mercy be discussed separately, where influx is the subject. This then is why it is said that through the ultimate degree of order there is, so to speak, a way in from the natural creation.

530. As has been stated, the names used in this chapter mean Churches, or what amounts to the same, doctrinal systems, for it is by virtue of its doctrine that a Church exists and takes its name. Thus Noah means the Ancient Church, or the doctrine that remained from the Most Ancient Church. The situation with Churches or doctrines has been stated already, namely that they dwindle away until nothing remains any longer of the goods and truths of faith. And when that point has been reached, the Church is in the Word called vastated. Nevertheless a remnant is always preserved, that is, some people are preserved, no matter how few, with whom the good and truth of faith persist. And unless that good and truth of faith were preserved with those people there would be no conjunction of heaven with the human race.

[2] As regards the remnants that reside with the individual, the fewer they are the less possible it is for the rational concepts and the factual knowledge he possesses to receive light; for the light of good and truth flows in from the remnants, or rather from the Lord by way of the remnants. If there were no remnants residing with a person, he would not be a human being, but someone far inferior to any animal. The fewer the remnants, the less he is a human being, while the more they are, the more he is a human being. Remnants are like a star in the sky; the smaller it is the weaker the light coming from it, but the greater it is, the brighter the light coming from it. The few things that did remain from the Most Ancient Church resided with those who constituted the Church called Noah. Those things were not however the remains of perception but of integrity, and also of doctrine deriving from the things of the Most Ancient Churches that were matters of perception. At that point therefore a new Church was raised up by the Lord. Being entirely different in disposition from the Most Ancient Churches, it is to be referred to as the Ancient Church, ancient from the fact that it existed at the last stage before the Flood and in the first period of time after it. This Church will in the Lord's Divine mercy be dealt with later on.
