671. 'Pairs of all you shall cause to enter the ark to keep them alive means the regeneration of these. This becomes clear from what has been stated in the previous verse, to the effect that truths cannot be regenerated except by means of goods and delights. Nor therefore can things of faith be regenerated except through those of charity. Hence the statement here about pairs of all having to enter, clearly meaning that both truths, which belong to the understanding, and goods, which belong to the will, were to do so. With someone who has not yet been regenerated an understanding of truth and a will for good do not exist but merely appear to do so, and are referred to as such in everyday speech. It is possible for rational truths and for facts to exist with that person, but these have no life. It is also possible for goods which merely look like those of the will, such as those present with gentiles or even with animals, to exist there. But these have no life either; they are merely semblances. With man such things are in no sense alive until he has been regenerated and they have in this way been made alive by the Lord. In the next life what has life and what does not is perceived very distinctly. Truth that has no life is perceived instantly as something material, all tangled and closed up, while good that has no life is perceived as something wooden, bony, and stone-like. But truth or good made alive by the Lord is open, living, and full of what is spiritual and celestial - open even from the Lord Himself. This applies to every idea and action, even to the smallest of either of them. This is why the statement is here made about pairs having to enter the ark to keep them alive.

299. A book written within and on the back. That this signifies the state of life of all in heaven and on the earth, in general and in particular, is evident from the signification of a book, in this case of the book of life, as denoting what is inscribed or implanted by the Lord in the spirit of man, that is, in the heart and soul, or what is the same thing, in the love and faith (concerning which see above, n. 199): hence by the book is here signified the state of life of all in heaven and on earth, and by its being written, is signified what is implanted by the Lord; (that to write signifies to implant, may be seen also above, n. 222); and from the signification of within and on the back, as denoting its being in the heart and soul, or in the love and faith. For with man and spirit love is within, because it constitutes his life; whereas faith, unless it is in his love, is not within, but behind or at the back; for the faith which is faith, makes entirely one with the love, for what a man loves belongs to his faith, but what he does not love does not belong to his faith. That appears, indeed, to be faith which any one thinks from the memory, and teaches from doctrine, but if he loves it only from a natural and not a spiritual love, it is the sight only of the thought of the external man, which sight counterfeits faith; but this faith, being without life before it is implanted in the internal man and its love, is not in the man, but behind him, or at his back. The faith implanted in the internal man and its love, is to believe and love the truth because it is truth, and not to love it chiefly for the sake of a reputation for learning, and of honour or gain therefrom. From these considerations it is evident what is signified by being written within and on the back.

[2] The subject treated of in this chapter is, that the Lord alone knows the states of the life of all in general and of each in particular, and that no one [knows this] besides Him. This is representatively set forth by the book written, which no one could open, read, and look into, but the Lamb alone, that is, the Lord. The reason why no one knows this except the Lord alone, is, because He is God alone, and because He formed the angelic heaven to the image of Himself, and man to the image of heaven: therefore He knows all things of heaven in general, and He who knows all things of heaven in general, also knows everything in particular; for a man who is in truths from good, and an angel, is an image of heaven, for he is a form of it; hence it also follows, that no one knows the states of any one in particular but he who knows the general state of all, for the one depends inseparably upon the other. But these things cannot be described in a few words; therefore see what is shown in the work concerning Heaven and Hell, where they are more distinctly and clearly described, in the following articles: That the Divine of the Lord makes heaven (n. 7-12); That every angel is a heaven in the least form (n. 51-58); That the whole heaven in the aggregate has reference to one man (n. 59-67); Similarly each society there (n. 68-72); That hence every angel is in a perfect human form (n. 73-77); That heaven, which is from the Divine Human of the Lord, in the whole and in part, has reference to man (n. 78-86); That there is a correspondence of all things of heaven with all things of man (n. 87-102); Concerning the conjunction of heaven with mankind (n. 291-302).

[3] It must be noted that here and elsewhere in the Word a book is mentioned, but by this a scroll (volumen) is meant; for in ancient times they wrote upon parchments, which were rolled together, and the parchment was called a book, and a scroll of a book, as may be seen in the Word.

As in Ezekiel:

"I looked, when behold, a hand sent unto me; and lo, in it a scroll of a book written within and without" (2:9, 10).

And in David:

"Then said I, Lo, I come; in the scroll of the book it is written of me" (Psalms 40:7).

Wherefore also, it is said in Isaiah:

"All the host of the heavens shall waste away, and the heavens shall be rolled together as a scroll" (34:4).

Also in the Apocalypse:

"The heaven departed, as a book when it is rolled together" (6:14).

From these considerations it can be known how the book, which John saw, was written within and on the back.
