As for the Lord’s actually appearing in heaven as the sun, this is something I have not simply been told by angels but have also been allowed to see a number of times; so I should like at this point to describe briefly what I have heard and seen97 concerning the Lord as the sun.
The Lord does not appear as a sun in the heavens, but high above them, and not directly overhead but in front of angels at a middle elevation. He appears in two places, in one for the right eye and in another for the left, noticeably far apart. For the right eye he looks just like a sun, with much the same fire and size as our world’s sun. For the left eye, though, he does not look like a sun but like a moon, with similar brilliance but more sparkling, and with much the same size as our earth’s moon; but he seems to be surrounded by many apparent lesser moonlets, each similarly brilliant and sparkling.
The reason the Lord appears in two places, so differently, is that he appears to people according to their receptiveness. So he looks one way to people who accept him through the good of love and another way to people who accept him through the good of faith. To people who accept him through the good of love, he looks like a sun, fiery and flaming in response to their receptivity. These people are in his heavenly kingdom. To people who accept him through the good of faith, though, he looks like a moon, brilliant and sparkling in response to their receptivity. These people are in his spiritual kingdom.a This is because the good of love corresponds to fire, so that fire, in its spiritual meaning, is love; while the good of faith corresponds to light, so that light, in its spiritual meaning, is faith.
The reason he appears to the eyes is that the deeper levels of the mind see through the eyes, looking from the good of love through the right eye and from the good of faith through the left eye.c You see, everything on the right side of an angel or one of us corresponds to what is good and yields truth, while everything on the left side corresponds to that truth that comes from what is good.d,98 “The good of faith” is, essentially, truth that comes from what is good.
