Portions from passages in Conjugial Love ~ Emanuel Swedenborg
... man is born natural that he may become spiritual; and so long as he remains natural he is in night, and as in sleep, respecting spiritual things; and that then he does not even know the distinction between the external natural and the internal spiritual man. ......
the Lord ... alone opens the internals of human minds and makes them spiritual; and He puts these [spiritual] within things natural in order that they [natural] also may derive a spiritual essence, as in fact they do if He [the Lord] is approached, and if the life is according to His precepts; which are in brief, that one should believe in Him and shun evils because they are of the devil and from the devil; and do goods because they are of the Lord and from the Lord; and do both as if of one's self, and at the same time believe that they are done by the Lord through him. The very reason why the Lord alone opens the internal spiritual man, and brings this into the external natural man, is that every man thinks naturally and acts naturally, and for that reason could not perceive anything spiritual and receive it into his natural if God had not put on the natural human, and made also that Divine. ...
...
... [the interiors of the mind], which in themselves are spiritual ... can be opened only by the Lord .... The real reason why they are opened by the Lord when He is acknowledged, and is approached as God of heaven and earth, and with those who live according to His precepts is, that otherwise there is no conjunction, and without conjunction there is no reception. There is the presence of the Lord with man, and there is conjunction with Him.
To go to Him brings presence, and to live according to his precepts effects conjunction.And His presence only is without reception; but presence and at the same time conjunction is with reception.
Concerning these matters I will relate this that is new from the spiritual world: There, every one is made present by thought about him; but no one is conjoined to another except from the affection of love, and the affection of love is insinuated by doing his words and his pleasure. This fact, familiar in the spiritual world, takes its origin from the Lord, in that He is thus present and is thus conjoined.
