Luke 13:22

‘And he went on his way through cities and villages, teaching, and journeying on to Jerusalem.'

Having established the principle Jesus then went out to put it into practise. He went through their cities and villages preaching, and this preaching would necessarily include the preaching of the Kingly Rule of God. Indeed in a sense that was what all His preaching was about, the Kingly Rule of God in its many forms. And as He did so He went on towards Jerusalem. For it was what He would accomplish at Jerusalem that would cause the triumph of the Kingly Rule of God.
