Apocalypse Revealed #121
121. "'And I will give him a white stone.'" This symbolizes truths supportive of and united to good.
A white stone has this symbolism because in cases requiring decision, votes used to be tallied by collecting stones, and white stones meant affirming votes. Affirming truths are symbolized here, because whiteness is predicated of truths (nos. 167, 379). Consequently a white stone symbolizes truths supportive of good. It means also truths united to good, because goodness attracts truths and unites them to itself. Indeed, all good loves truth and joins to itself such truth as is in harmony with it, and especially so the goodness of celestial love. This so unites truth to itself that they form an indivisible whole.
For this reason celestial people view truths from the perspective of good. They are the people meant by those who have the law written on their hearts, of whom we read in Jeremiah:
I will put My law in the midst of them and write it on their hearts... No more shall each teach his companion, or each his brother, saying, "Know Jehovah," for everyone shall know Me... (Jeremiah 31:33-34)
Of such a character are all the inhabitants of the third heaven. They do not talk about truths from some memory of them, but clearly see truths whenever they hear other people talking about them, and especially when they read the Word. That is because they possess a real marriage of goodness and truth.
People become of this character in the world if they have turned to the Lord alone and done good works because they accord with the Word's truths.
Something regarding these angels may be seen in the book Heaven and Hell, nos. 25, 26, 270, 271.
