During Jesus Christ’s ministry and later in the ministry of the church, demons are subject to his authority.
All spiritual powers are subject to Jesus Christ, who has supreme authority
Eph 1:19-22 Also see Ro 8:38; Eph 3:10; Col 1:16; 2:10,15
Demons are powerless before Jesus Christ
Demons can only do what he permits Mt 8:31-32 pp Mk 5:12-13 Lk 8:32-33
Demons obey his command Mt 17:18 pp Mk 9:25-26 Lk 9:42 Also see Mt 9:33-34; Mk 1:34; 16:9; Lk 11:14
Demons disperse at his word Mk 9:25 Also see Mk 1:25 Lk 4:35
The name of Jesus Christ has power against demons
Jesus Christ’s name is used by his disciples Mk 16:17. Also see Mk 9:38-39 Lk 9:49-50; Lk 10:17; Ac 16:18
Jesus Christ anticipates the misuse of his own name Mt 7:22-23. Also see Ac 19:13-16, an example where Jesus’ name is used in cases of demon-possession–but not by Jesus Christ’s disciples, and not successfully
Jesus Christ’s disciples have delegated power over demons
In Jesus Christ’s own lifetime Mt 10:1 Also see Mt 10:7; Mk 3:14-15; 6:7 Lk 9:1; Mk 6:13; Lk 10:17,19
In the ongoing ministry of the church, Mk 16:17 Also see Ac 5:16; 8:7; 16:18; 19:12
Others will attempt to drive out demons
Mt 12:27 Lk 11:19; Mk 9:38 Lk 9:49; Ac 19:13-15
The final punishment of demons
2Pe 2:4; Jude 6
Lord Jesus, I believe you are the son of God, and you died for my sins and rose again from the dead, I trust you for cleansing and forgiveness, and you have received me as a Child of God. If there is any resentment or unforgiveness for anyone, I lay it at your feet and ask you to forgive me. I ask your forgiveness for being involved in other religions, witchcraft, or the occult seeking other gods. I acknowledge this as sin and loose myself right now in Jesus name. And now, Lord Jesus, I come to and yield my body, mind, and spirit to you. I give you my all. Come into my heart and be my personal Saviour. I surrender my tongue to you to be an instrument of righteousness to worship you in a new language. By faith, I receive it now, Lord in Jesus name. Amen.
