Yes we do. “The battle is the Lord’s. Stand still and see the salvation of the Lord.” Also, those who are called, to intercede in powerful intercessory prayer which turned and defeated the powers of darkness in WWII and can do the same here and now.
Also, “What hath God wrought?”
I should clarify; those of us walking with God know how to fight but the majority of people, even many that call themselves Christians, do not know how.
