Matthew 4:17
From that time Jesus began to preach, saying, Repent, for the kingdom of heaven is at hand. Jesus begins his public preaching with the exact message John preached (3:2): repent, for the kingdom of heaven is at hand. The continuity is deliberate — Jesus does not announce a new message but continues and embodies the one John prepared. The from that time marks a narrative turning point: from this moment, the public ministry is underway. The kingdom that John announced as approaching is now being proclaimed by the king himself. Luke 4:18–21 records Jesus' fuller inaugural address citing Isaiah 61; Matthew's summary is tighter: the kingdom requires repentance, and the kingdom is here.
