Revelation 19:12-14

Revelation 19:12-14. His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself. And he was clothed with a vesture dipped in blood: and his name is called The Word of God. And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.

All his true ones, all his faithful ones, all his saints, whether ministers or not, the heavenly armies, "followed him upon white horses, clothed in fine linen, white and clean." Holiness is their armor, light is the panoply that they wear as they go forward to this holy war.
