I agree demons want nothing to do with Jesus they flee at the mention of His name. Because they know who He is and understands the Judgement they are already under their is no escape for them.<quoted text>
Commentary by Matthew Henry "The devils have nothing to do with Christ as a Saviour; they neither have, nor hope for any benefit from him. Oh the depth of this mystery of Divine love; that fallen man has so much to do with Christ, when fallen angels have nothing to do with him! Heb 2:16."
This is the reason the swine/demons ran into the Sea of Galilee, known as the Abyss....I am glad this writer mentions it, but didn't understand the whole spiritual intent of this teaching in context.
First of all Jesus never did anything for nothing, He freed a man from demon possession, proved to people He is who He said He is and has the power to do what only God Himself can do.
And also proved there are some people willingly follow after the things of satan.
there is more going on here then just Jesus casting legions (numerious devils) into a bunch of swines.
The demons drove the swines into the sea to flee from Jesus.
