Dear saints, let us pray that the saints would realize that the preaching of the gospel, which delivers men out of the power and kingdom of Satan, is a spiritual warfare (Josh. 6:1-5; Acts 26:18; 2 Tim. 2:3).
First, we need to see that toward Satan the preaching of the gospel is a spiritual battle…If we would meet God’s need today, we need to see that God’s preaching of the gospel through His people on the earth is a matter of engaging in spiritual warfare. Thus, a person who preaches the gospel must be a soldier.
The gospel of God is a spiritual gospel, and to preach this gospel is to fight a spiritual battle. Such a battle is not in the physical realm but in the spiritual realm, because the preaching of the gospel is to plunder from under Satan’s hands, from under Satan’s authority, and from Satan’s usurpation those whom God predestinated and desires to save. To preach the gospel is not merely a matter of evangelizing but a matter of fighting a battle. As the gospel is being preached, God is plundering through His church those who are being usurped by Satan. (Collected Works of Witness Lee, 1959, vol. 2, “Christ Being the Burden of the Gospel,” ch. 1, p. 420)
