“When the Lord Jesus died, all the power of Satan was destroyed. But what can actually cause Satan to lose his power in heaven? All of his power can be brought to an end by God’s children on earth repeatedly dealing with him, instance after instance. When the demons have been subdued many times in the name of the Lord Jesus, Satan will be cast down.
Suppose that we have a balance that is used for weighing. On one side of the balance there is Satan. Since we do not know how much Satan weighs, we must keep adding weight on the other side of the scale. Each time we deal with Satan we add more weight to the other side. When the weight is increased to a certain point, Satan will be moved. In the beginning, as we continue to add weight to the other side, it is seemingly of no use. But each addition of weight is valuable. Finally, when the last amount of weight is added, the balance will start to move. We do not know who will add the last amount of weight, but all the weight, that which is added in the beginning and that which is added at the end, produces the effect. The work of the church is to resist the work of Satan so that together we can cast out the demons. This is why Satan will do anything in his power to hinder us from being overcomers.
Casting out demons does not necessarily mean that when we encounter a demon we should confront him. Casting out demons means that we cast out all the work and power of the demon. We lay hold of the authority of the Lord and stand fast in our position. One brother adds a little weight, and another brother adds a little more weight. Then one day Satan will be cast down from heaven. God does not work directly by His own hand to cause Satan to fall from heaven. It would be very easy for Him to do this work, but He does not. He has entrusted this work to the church. Oh, how pitifully the church has failed in this matter and been unable to do it! This is why there must be the overcomers standing in the position of the church to do God’s work. When the overcomers stand in the church’s position and do the work which the church should have done, the result will be: “Now has come the salvation and the power and the kingdom of our God and the authority of His Christ.” The man-child in Revelation 12 consists of the overcomers who stand on behalf of the church. Therefore, as soon as the man-child is caught up, Satan is cast down from heaven and the kingdom comes.”
