Mark 1:5
The whole Judean countryside and all the people of Jerusalem went out to him — Mark's hyperbole communicates the scale of John's impact. The confession of sins while being baptized is the decisive action: these are people publicly owning their failure and aligning themselves with the coming kingdom through a visible, irreversible act. The entire geographic center of official Judaism — Judea and Jerusalem, the temple and its leadership — is drawn to this wilderness prophet who bypasses the temple system entirely. The irony is structural: the religious establishment that will ultimately reject Jesus is populated by people who were baptized in repentance awaiting him.
