Dear saints, let us pray that the saints would see that the Lord Jesus in His gospel service frees human beings from Satan’s usurpation by the Spirit of God for the kingdom of God (Matt. 12:28 and note 28-1; Luke 11:20; Mark 1:23-25).
The fallen angels work with Satan in the air (Eph. 2:2; 6:11-12), and these demons, the unclean spirits, move with him on the earth. Both act evilly upon man for the kingdom of Satan. The possession of people by demons signifies Satan’s usurpation of man, whom God created for His purpose. The Lord Jesus came to destroy the works of Satan (1 John 3:8), and in His earthly ministry He cast out demons from the possessed people (Mark 1:34, 39; 3:15; 6:7, 13; 16:17) so that they might be delivered from Satan’s bondage (Luke 13:16), out of Satan’s authority of darkness (Acts 26:18; Col. 1:13), into God’s kingdom (Mark 1:15).
In Matthew 12:28 the Lord Jesus says, “If I by the Spirit of God cast out demons, then the kingdom of God is come upon you.” The Spirit of God is the power of the kingdom of God. Where the Spirit of God is in power, there the kingdom of God is, and there the demons have no ground. By the Lord’s word here we see that the battle fought for the kingdom is not fought by man alone but by a man with the Spirit of God. Therefore, the Lord Jesus said that He cast out demons by the Spirit of God and that this is the coming of the kingdom of God. (The Conclusion of the New Testament, msg. 65, p. 694, by Witness Lee)
