Matthew 14:4

For John said unto him, &c.— Possessed of great credit with Herod, and with the people, it is not possible to suppose that the Baptist would have incurred Herod's jealousy and displeasure, had he been an impostor, and an associate of a pretended Messiah,—for fear of blasting at once all his preconcerted designs. Certainly, he would now, more than ever, have employed all his art to keep the influence that he had acquired with the king and the people. But how opposite to all this was his conduct: at this critical point of time, in this peculiar situation, when both his own and his confederate's interest absolutely required him to act in the manner just mentioned, he even proceeded to reprove Herod himself for the wickedness of his life.An impostor, in John's particular situation, could not but have reflected, at the first thought of so dangerous a step as that which occasioned his death, that it was not his own immediate assistance only of which his associate would be deprived by his destruction,—though this alone would have been sufficient to prevent him from adopting it; but he would besides have considered, that his own imprisonment and death would probably strike such a panic into the people, however zealous they had before been in his favour, aswould refrain them from listening afterwards to Jesus, or payingthe same regard which they might otherwise have done to his pretensions: nay, nothing was more probable, than that John's public ministry, being put to so ignominious an end, would evendestroy that good opinion of John himself, which they had hitherto entertained, and induce them to believe, that, notwithstanding his fair outside, he could be no better than an impostor. For by what arguments could John think it possible, that the Jews would persuade themselves hewas really sent to be the divine forerunner of this triumphant Messiah, when they should have seen him seized by Herod's order, imprisoned, and put to death? Besides, therefore, John's regard to his own success, his liberty, andeven his life itself, which no impostor can be thought desirous of exposing to certain destruction for no reason; his connection with Jesus, if they were deceivers, and the necessary dependence of both upon the mutual success and assistance of each other, must unquestionably have restrained John from provoking at this time the inveterate hatred of Herodias, and drawing on himself Herod's violent suspicion and displeasure. So that the remarkable behaviour of John, in this important particular, and at so critical a conjuncture, affords us one of the strongest presumptive proofs imaginable, that neither he nor Jesus could possibly be deceivers.
