John 8:49

Jesus answered, I have not a devil
He takes no notice of the first charge and scandalous character, that he was a Samaritan; it being so notorious to all the Jews, that he was not; but was, as they supposed, a Galilean, and of Nazareth; and besides, this was a term of reproach, which they gave to any man, that they had no good opinion of; just as we call a man a Turk, or a Jew; not meaning that he is in fact such an one, but behaves like one: to the other Christ replies, that he had not a devil, had no conversation with one, nor was he possessed or assisted by him, or was mad, and acted the part of a madman: in proof of which he observes,

but I honour my Father;
by ascribing his doctrine and miracles to him, by doing his will, seeking his glory, and speaking well of him; all which he would not, had he been in confederacy with the devil; for no man can be familiar with him, or be assisted by him, and honour God; nor could a man out of his senses do all this:

and ye do dishonour me:
by such wicked charges, and scandalous imputations: and Jews, who deny Jesus to be the Messiah, and treat him in this opprobrious manner, are not the only persons that dishonour Christ; there are many that are called by his name, who greatly dishonour him; some by their bad principles, and others by their evil practices: such highly reflect upon him, who deny his proper deity, and eternal sonship; who assert, that he is only God by office, and did not exist before his incarnation; who despise and reject his righteousness, submit not to it, but establish their own; who account his blood as common and useless, and speak disrespectfully of his sacrifice and satisfaction; and who consider his sufferings and death only as an example to men, and for the confirmation of his doctrine, but not as in the room and stead of his people, to answer and satisfy divine justice for them: and others they dishonour him, though they talk much of him, and pretend to faith in him, and love to him, and hope of eternal life by him, through their scandalous lives and conversations; dishonour his name and Gospel; give the enemy an occasion to reproach and blaspheme, and by reason of them, the ways and truths of Christ are evil spoken of.
