Isaiah 9:7

His ruling authority will grow,

and there'll be no limits to the wholeness he brings.

He'll rule from the historic David throne

over that promised kingdom.

He'll put that kingdom on a firm footing

and keep it goingWith fair dealing and right living,

beginning now and lasting always.

The zeal of God-of-the-Angel-Armies

will do all this.

God wants to bring about a complete change. The gospel is not just a gospel of salvation and the four spiritual laws. It is instead the gospel of the whole kingdom being brought back to completion. He will be the one leading this whole thing and establishing it. We will be His tools and vessels.
