Apocalypse Revealed#165
165. "'You have a few names even in Sardis.'" (3:4) This symbolically means that they also have among them some people who do have life in their worship.
A few names means, symbolically, some who are of such a character as now described, for a name symbolizes someone's character. That is because everyone in the spiritual world is named in accordance with his character (no. 81). The character of the people described now is that they have life in their worship.
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.
