Apocalypse Revealed # 25
25. And every eye will see Him. This symbolically means that all those will acknowledge Him who possess, from an affection for it, an understanding of Divine truth.
In the spiritual sense an eye means not an eye but the intellect. Consequently the declaration that every eye will see. This symbolically means that all those will acknowledge Him who possess, from an affection for it, an understanding of Divine truth, since it is they alone who understand and acknowledge. Others, indeed, see and also understand, but they do not acknowledge.
Those who acknowledge are symbolically meant because it is next said that they also who pierced Him will see, meaning people who are caught up in falsities.
To be shown that an eye symbolizes the intellect, see no. 48 below.
