Jesus fought and conquered

“He [Jesus] fought and conquered. On the one hand, he was man who struggled for his fathers and through his obedience cancelled their disobedience. On the other hand, he bound the strong one and freed the weak and bestowed salvation on his handiwork by abolishing sin. For he is our compassionate and merciful Lord who loves mankind … Had not man conquered man’s adversary, the enemy would not have been conquered justly. Again, had it not been God who bestowed salvation we would not possess it securely.”
― Irenaeus of Lyons, Against Heresies 3
