Apocalypse Revealed#168
168. "'He who overcomes shall be clothed in white garments.'" (3:5) This symbolically means that anyone who is reformed becomes spiritual.
To be shown that someone who overcomes means, symbolically, someone who is reformed, see no. 88 above. And to be shown that being clothed in white garments means, symbolically, to become spiritual through truths, see nos. 166, 167.
All those people become spiritual who possess truths and live according to them.
John 19:23-24
23
Then the soldiers, when they had crucified Jesus, took his garments, and made four parts, to every soldier a part; and also his coat: now the coat was without seam, woven from the top throughout.
24
They said therefore among themselves, Let us not rend it, but cast lots for it, whose it shall be: that the scripture might be fulfilled, which saith, They parted my raiment among them, and for my vesture they did cast lots. These things therefore the soldiers did.
