When we speak of spiritual warfare, let us not think in terms of the abstract. “They overcame him because of the blood of the Lamb.” What do you take that to mean? ― that they were a people of a phraseology about the blood and they started hurling their phraseology at the Devil? Well, phraseology, even about the Blood, has no effect on him. “They overcame him because of the blood of the Lamb.” Whom did they overcome? The Accuser of the brethren, who accused them day and night. How do you overcome an accuser? Only by having a better case than he has. You have to have a good case, and the Blood of the Lamb represents that in a mighty way. Our legal standing because of the Blood of the Lamb puts the enemy out of court if only faith will hold to it. And we must not think in geographical terms of Satan being cast down from somewhere high up and coming crashing to the earth. This is spiritual warfare. We have to get this spiritual sense and idea of things. Our soulical mentality is always drawing pictures of places, positions, spaces, but we have to understand that this is a spiritual matter that Satan can, in effect, be cast from the highest heights to the lowest depths without any geographical factor coming in at all.
You may have a person against you who lays a charge at your door, and thinks he has a very strong case. But you happen to have a case which undercuts that and tears it to pieces, and he goes down before you in utter collapse; he comes from a tremendous soul height to a very great depth. That is not a geographical thing but a spiritual. This is spiritual warfare, not geographical. “Our wrestling is not against flesh and blood” (Eph. 6:12), it is not in the realm of the physical and geographical at all. It is spiritual; you can call it moral if you like and the Blood represents a legal case, and Satan can be cast down from heaven countless times in one day. You cannot do that literally; it can only be understood spiritually. A million people all over this earth may cast him down in one day at different moments of the day. As they stand by faith on the case that the Blood provides, they have a mighty and triumphant answer. That is how spirituality works out in warfare. Christ works spirit-wise. Soul cannot cast out soul, and the soul cannot cast out the Devil because the Devil has already got it in his hand. Satan has obtained ground in our souls, but in our renewed, born-again spirits he has no place. The evil spirit behind everything can only be overcome by a spirit strengthened with might by the Spirit of God, and that means by a subduing of the soul to the spirit.
