King David the Theonomist

"I will look with favor on the faithful in the land, that they may dwell with me; he who walks in the way that is blameless shall minister to me. No one who practices deceit shall dwell in my house; no one who utters lies shall continue before my eyes. Morning by morning I will destroy all the wicked in the land, cutting off all the evildoers from the city of the Lord." 

- Psalm 101:6-8 

The passage above was written by King David. Notice that he rejects the wicked from both his own house, i. e., from among his family, and in the land, i. e., his political realm of Israel. 

While this was the common Christian view in history, including in the colonial and early independence periods of the United States. Yet, today, even professing Christians, those who claim to believe in God's Word, have accepted the view of the humanists that God has no say in the laws of the land. Under the influence of pietism and dispensationalism, Christians advocate any law except that of God. 

What has that gotten us? Abortion, gunfights in the streets and in our schools, burning down our own cities. How has that been a winning strategy? 

In contrast, David, the paradigm of the believing magistrate, took it as his responsibility to eliminate the wicked from the land over which God had given him charge.
