How do you respond when told to "repent"?

In those days John the Baptist came preaching in the wilderness of Judea, “Repent, for the kingdom of heaven is at hand.” For this is he who was spoken of by the prophet Isaiah when he said,

    “The voice of one crying in the wilderness:
    ‘Prepare the way of the Lord;
        make his paths straight.’”

God has brought his Redeemer out of the smoldering chaos of this world to rescue his people.

"Out of Egypt I called my son."

"A voice was heard in Ramah,
        weeping and loud lamentation,
    Rachel weeping for her children;
        she refused to be comforted, because they are no more.”

He will be called a Nazarene.
