Apocalypse Explained #664
664. And after three days and a half.- That this signifies when completed, thus the end of the old church, and the beginning of a new church, is evident from the signification of three days and a half, as denoting fulness or completion at the end of the old church, when there is the beginning of a new church, concerning which see above (n. 658). The reason why it is said, after three days and a half, is, that days, in the Word, signify states, here, the last state of the church. For all times, in the Word, as hours, days, weeks, months, years, and ages, signify states in the Word, as in this case, the last state of the church, when there is no longer any good of love or truth of faith remaining. Because days signify states, and since in the first chapter of Genesis the establishment of the Most Ancient Church is treated of which was accomplished successively from one state to another, therefore it is said there that there was evening and there was morning the first, the second, the third, the fourth, the fifth, and sixth days, unto the seventh, when it was completed (Genesis 1:5, 8, 13, 19, 23, 31), and the days there do not mean days, but the successive states of the regeneration of men at that time, and the consequent establishment of the church with them. So also elsewhere in the Word.
Arcana Coelestia #780
780. 'Of all flesh in which there was the spirit of life 1 means a new creature, or the fact that they received new life from the Lord. This becomes clear from the meaning of 'flesh' as all mankind in general and a bodily-minded person in particular, as stated and shown already. Consequently 'flesh in which there was the spirit of life' 1 means a person who has been regenerated, for the Lord's life, which is the life of charity and faith, is there within his proprium. Nobody is anything more than flesh, but when the life of charity and faith is breathed into him by the Lord, his flesh in that case is made alive, becomes spiritual and celestial, and is called 'a new creature', Mark 16:15, from having been created anew.
