Jesus declaring and demonstrating His authority

Jesus spoke as the author of God's word - John 1:1, Jesus is the embodiment of God's word - Revelation 19, John 14:16

An effective messenger will always point you to the Word of God - II Timothy 2:1-2

Is your focus on the devil and demons, or on the Deliverer?

James 4:7-8, James 2:19, Psalm 91
