12 And His eyes are a flame of fire, and upon His head are many diadems; and He has a name written upon Him which no one knows except Himself.
13 And He is clothed with a robe dipped in blood; and His name is called The Word of God.
14 And the armies which are in heaven, clothed in fine linen, white and clean, were following Him on white horses.
15 And from His mouth comes a sharp sword, so that with it He may smite the nations; and He will rule them with a rod of iron; and He treads the wine press of the fierce wrath of God, the Almighty.
16 And on His robe and on His thigh He has a name written, “KING OF KINGS, AND LORD OF LORDS.”
We normally think of God the Father as the Almighty. But this title, which means possessing of all power and ruling with all authority, can apply in most contexts to the Godhead as a whole, and the clearly in this context the Jesus.
Rev. 19 presents Jesus as a mighty and unstoppable warrior, an avenging judge and mighty king in the conclusion of the war that the book of Revelation reveals. The end of the conflict is the total destruction of the enemies of God.
Consider Jesus who an almighty conquering warrior fighting for us.
