"It is strange that any should interpret this as speaking of Jesus’ sufferings on the cross, yet that is how many interpreters view it. The cross, however, does not reveal warfare, but the great love, reconciliation, and redemption of God in Christ! Furthermore, in the scene above it is not His own blood that is shed in weakness and in meekness and in sacrifice, but the blood of foes trampled in wrath. He is on His way to battle! And “every battle of the warrior is with confused noise and garments rolled in blood” (Isa. 9:5). The language is symbolic, of course. Jesus does not wield a literal sword of steel; His sword is the sword of the spirit, which is the word of God. He does not go out physically killing multitudes of people, and soaking His garment with their blood. Rather, His warfare is spiritual, He slays the enemies within man, which appear as the man, but are not the man that God intends. Oh, yes! He slays men, but it is the natural man — the human consciousness, the carnal mind, the ego, self-will, lust, deception, fear, rebellion, bondage, and every sin of the old Adamic man. Wielding His powerful sword of the spirit He comes upon the world of natural, carnal-minded, sinning men, and He comes to judge and to make war! His flaming eyes picture to us the holy passion that burns in His bosom at this moment, now that He is ready to subdue the earth and establish His righteous kingdom in the hearts of all men everywhere!"
