Let us finish in Revelation 19. Because the day of the Commander of the armies of the Lord is not over.
One of the last acts of this age features the Lamb of God, the Word of God, the One we know as Jesus Christ, in divine warrior mode, bringing God's wrath upon His enemies, in justice. You might want to write down Psalm 110:1:2, 5-6. There it shows in the poetic language of the Psalms, Him doing the exact same thing when God says, Sit on Your throne and make My enemies Your footstool.
He strikes the nations with the sharp sword of His mouth, and notice it says He Himself will rule them with a rod of iron. He Himself treads the winepress of the fierceness and wrath of Almighty God. He does it personally. He does not give it off to some junior. He is going to do this Himself. And as I mentioned before, He never loses a battle. And with His victory, He will bring peace to the earth and usher in God's Kingdom and a thousand years of prosperity and goodness for all.
So God is a divine warrior because men and angels are at war with Him - that is, fallen angels. He meets them on the field of battle in judgment and in wrath, and His righteous interventions bring justice to the iniquitous and peace to the faithful. And there is nothing wrong with that.
