Using the word of the Lord to manage this world

1 Kings 16:8-14
Zimri, one of his officials, who had command of half his chariots, plotted against him. Elah was in Tirzah at the tie, getting drunk in the home of Arza. Zimri came in, struck him down and killed him. Then he succeeded him as king.
As soon as he began to reign and was seated on the throne, he killed off Baashs'a whole family. He did not spare a single male, whether relative or friend. So Zimri destroyed the whole family of Baasha, in accordance with the word of the Lord spoken against Baasha through the prophet Jehu.
His successor, Elah, rules for two years before his assassination by Zimri.
Why?
For those kings are against the way of the Lord, so they plotted the position and got it by violent, so they were be killed and token by violent either. There were not peace and safety in the county without blessing of the Lord.
Kings of Israel  who did anything by their desires and making the God of Isreal angry with their stupid idols.
How?
God choose the one who fear the Lord to be authorized in higher position. Using the word of the Lord to manage this world.
