From that time Jesus began to preach, and to say,
Repent: for the kingdom of heaven is at hand.

John Chrysostom
AD 407
From that time: what time? After John was cast into prison. And wherefore did He not preach to them from the beginning? Indeed what occasion for John at all, when the witness of His works was proclaiming Him?
That hence also you might learn His dignity; namely, that as the Fathers, so He too has prophets; to which purpose Zacharias also spoke; And you, child, shall be called a prophet of the Highest. Luke 1:76 And that he might leave no occasion to the shameless Jews; which motive He himself alleged, saying, John came neither eating nor drinking, and they say, he has a devil. The Son of Man came eating and drinking, and they say, Behold a man gluttonous and a winebibber, a friend of publicans and sinners. But wisdom is justified of her children.
And moreover it was necessary that what concerned Him should be spoken by another first and not by Himself. For if even after both testimonies and demonstrations so many and so great, they said, You bear record of Yourself, Your record is not true: John 8:13 had He, without John's saying anything, come into the midst, and first borne record Himself; what would they not have said? For this cause, neither did He preach before John, nor did He work miracles, until John was cast into prison; lest in this way the multitude should be divided. Therefore also John did no miracle at all; that by this means also might give over the multitude to Jesus, His miracles drawing them unto Him.
Again, if even after so many divine precautions, John's disciples, both before and after his imprisonment, were jealously disposed towards Him, and the people too suspected not Him but John to be the Christ; what would not the result have been, had none of these things taken place? For this cause both Matthew distinctly notes, that from that time He began to preach; and when He began His preaching, He Himself also taught this same doctrine, which the other used to preach; and no word as yet concerning Himself does the doctrine which he preached say. Because it was for the time a great thing even for this to be received, forasmuch as they had not as yet the proper opinion about Him. Therefore also at the beginning He puts nothing severe or grievous, as the other did, mentioning an axe, and a tree cut down; a fan, and a threshing-floor, and unquenchable fire; but His preludes are gracious: the Heavens and the kingdom there are the good tidings which he declares to His hearers.
