Thus the same as before is established yet more abundantly; for He says, So far am I from having the Devil for my ally, that I rather am at war with him, and bind him; and in that I cast out after this sort, I therein spoil his goods. Thus He proves the very contrary of that they strove to establish.
He thus reiterates the same point with even greater emphasis; stating that he is so far opposed to the Devil's involvement that he rather sees himself as an enemy, and overcomes him. This is further illustrated by His actions, where He drives out evil in a similar way, thereby depriving the Devil of his possessions.
