Isaiah 32:1 (NKJV)
1 Behold, a king will reign in righteousness, And princes will rule with justice.
This passage (vv1-8) is about the quality of government that will characterize the rule of the king of the new age. He and those who rule with him will be those associated with righteousness and justice. "That is, they will reflect, in the way they exercise their rule, the very character of God himself (i.e.5:16)." - Webb - p136.
Imagine a world of kingdoms ruled by kings and princes who reigned in righteousness and with Word-defined justice. Now pray the Lord's prayer again - with more fervor!
