This Second Coming of the Lord is not a Coming in Person, but in the Word, which is from Him, and is Himself .
It is written in many places that the Lord will come in the clouds of heaven; but as no one has known what was meant by the clouds of heaven, men have believed that He would come in them in Person. That the clouds of heaven mean the Word in the sense of the letter, and that the glory and power in which He will also then come mean the spiritual sense of the Word, has hitherto been hidden; because no one hitherto has even conjectured that there is any spiritual sense in the Word, such as this in itself is. Now, since the Lord has opened to me the spiritual sense of the Word, and has granted me to be in company with angels and spirits in their world, as one of them, it is disclosed that by the clouds of heaven the Word in the natural sense is meant, and by power the Lord’s might through the Word. That the clouds of heaven have this signification may be seen from these passages in the Word:—”There is none like unto the God of Jeshurun, who rideth upon the heaven, and in His greatness upon the clouds” (Deut. xxxiii. 26); “Sing unto God, praise His name, extol Him who rideth upon the clouds” (Ps. lxviii. 5); “Jehovah rideth upon a swift cloud” (Isa. xix. 1).
That the Lord is the Word is very certain from these words in John: “In the beginning was the Word, and the Word was with God, and the Word was God, … and the Word was made flesh” (i. 1,14). The Word here means Divine Truth; for Divine truth among Christians is from no other source than the Word. It is the fountain whence all churches bearing the name of Christ draw living waters in their fulness although it is as in a cloud, in which its natural sense is, yet it is in glory and power, in which its spiritual and celestial sense is. It has been shown in the chapter on the Sacred Scripture, and in the chapter on the Decalogue or Catechism, that there are three senses in the Word, the natural, the spiritual, and the celestial, one within another. It is therefore clear that in John the Word means Divine Truth…. From all this it is plain that now also the Lord will appear in the Word. The reason why He will not appear in person is, that since His ascension into heaven He is in the glorified Human and in this lie cannot appear to any man unless He first open the eyes of his spirit; and these cannot be opened with any one who is in evils and thence in falsities; thus not with any of the goats which He sets at His left hand. Therefore when He manifested Himself to the disciples He first opened their eyes; for it is said, “And their eyes were opened, and they knew Him; and He vanished out of their sight” (Luke xxiv. 31). The same occurred with the women at the sepulchre after the resurrection; and therefore they then also saw angels sitting in the sepulchre and talking with them, whom no man can see with the material eye. Neither did the apostles see the Lord in the glorified Human before the Lord’s resurrection with the eyes of the body, but in the spirit,—which appears after waking as if it were in sleep. This is evident from His transfiguration before Peter, James, and John, in that “their eyes were heavy with sleep” (Luke ix. 32). It is therefore vain to think the Lord will appear in person in the clouds of heaven but He will appear in the Word which is from Him, thus which is Himself. (TCR n. 776, 777)
This Second Coming of the Lord is effected by means of a Man, to whom the Lord has manifested Himself in Person, and whom He has filled with His Spirit, to teach the Doctrines of the New Church from Himself, through the Word
Since the Lord cannot manifest Himself in Person, as shown just above, and yet has foretold that He would come and establish a New Church, which is the New Jerusalem, it follows that this will be effected by means of a man, who is able not only to receive the doctrines of that church into his understanding, but also to publish them by the press. I testify in truth, that the Lord manifested Himself to me His servant, and sent me to this office; and that afterwards He opened the sight of my spirit, and so intromitted me into the spiritual world, and has granted me to see the heavens and the hells, and also to converse with angels and spirits, and this now continually for many years; likewise that from the first day of that calling I have not received anything whatever relating to the doctrines of that church from any angel, but from the Lord alone, while I was reading the Word.
To the end that the Lord might continually be present, He has opened to me the spiritual sense of His Word, in which Divine Truth is in its light. And in this light He is continually present; for His presence in the Word is no otherwise than by the spiritual sense. By the light of this He passes through into the shade in which the sense of the letter is; comparatively as the light of the sun in the daytime does through an interposing cloud. (TCR n. 779, 780)
