A selection of verses showing how God's special person will improve our world.
The prophet Isaiah foretells how he will have a strong, endless, just government:
6 For a child is born to us. A son is given to us; and the government will be on his shoulders. His name will be called Wonderful Counsellor, Mighty God, Everlasting Father, Prince of Peace. 7 Of the increase of his government and of peace there shall be no end, on David’s throne, and on his kingdom, to establish it, and to uphold it with justice and with righteousness from that time on, even forever. The zeal of the LORD of Armies will perform this.
He also says that, having the Lord’s influence, his rule will be wise, and considerate of the poor:
2 The LORD’s Spirit will rest on him:
the spirit of wisdom and understanding,
the spirit of counsel and might,
the spirit of knowledge and of the fear of the LORD.
3 His delight will be in the fear of the LORD.
He will not judge by the sight of his eyes,
neither decide by the hearing of his ears;
4 but he will judge the poor with righteousness,
and decide with equity for the humble of the earth.
He will strike the earth with the rod of his mouth;
and with the breath of his lips he will kill the wicked.
The prophet Micah gives more details of his firm but kind rule:
2 Many nations will go and say,
“Come! Let’s go up to the mountain of the LORD,
and to the house of the God of Jacob;
and he will teach us of his ways,
and we will walk in his paths.”
For the law will go out of Zion,
and the LORD’s word from Jerusalem;
3 and he will judge between many peoples,
and will decide concerning strong nations afar off.
They will beat their swords into ploughshares,
and their spears into pruning hooks.
Nation will not lift up sword against nation,
neither will they learn war any more.
4 But they will sit every man under his vine and under his fig tree;
and no one will make them afraid:
For the mouth of the LORD of Armies has spoken.
The book of Revelation tells us that God plans to make our world a much better place:
3 I heard a loud voice out of heaven saying, “Behold, God’s dwelling is with people, and he will dwell with them, and they will be his people, and God himself will be with them as their God. 4 He will wipe away every tear from their eyes. Death will be no more; neither will there be mourning, nor crying, nor pain, any more. The first things have passed away.”
