Isaiah's understanding of
the events and the goal of history connect with his hope of the coming of a
righteous king descended from David. The kings whom he knew, all descendants of
David, were disappointing and lacked the deep understanding which Isaiah had of
the character of the God they claimed to obey. We can understand how Isaiah and
his small group of disciples looked hopefully to the future, affirming the
coming rule of God when there would be joy and peace and the end of all
in-justice and evil, as the righteous descendant of David rules on behalf of
God who gives him wisdom and knowledge. The righteous descendant of David is
best described as a ruler or governor, rather than 'king'. God is the true King
of the earth and he gives authority to the anointed ruler of the family of
David to act for him. We should note that Isaiah thought in terms of God's rule
extending over the world in a practical and physical way. The blessings of
God's rule would be experienced through the government of the righteous ruler
in the earthly lives of people. Jerusalem was to be the purified centre of the
government of the righteous ruler. Jerusalem was to be the religious centre for
all nations who would come there to learn of God (2: 2-4 and 11 : 1-9).
