Arousing God anger by the things he did

1 Kings 15:25-16:14 

Nadab son of Jeroboam became king of Israel in the second year of Asa king of Judah, and he reigned over Israel two years. He did evil in the eyes of the Lord, following the ways of his father and committing the same sin his father had caused Israel to commit.

Baasha son of Ahijah from the tribe of Issachar plotted against him, and he struck him down at Gibbethon, a Philistine town, while Nadab and all Israel were besieging it. Baasha killed Nadab in the third year of Asa king of Judah and succeeded him as king.

As soon as he began to reign, he killed Jeroboam’s whole family. He did not leave Jeroboam anyone that breathed, but destroyed them all, according to the word of the Lord given through his servant Ahijah the Shilonite. This happened because of the sins Jeroboam had committed and had caused Israel to commit, and because he aroused the anger of the Lord, the God of Israel.

Then the word of the Lord came to Jehu son of Hanani concerning Baasha: “I lifted you up from the dust and appointed you ruler over my people Israel, but you followed the ways of Jeroboam and caused my people Israel to sin and to arouse my anger by their sins. So I am about to wipe out Baasha and his house, and I will make your house like that of Jeroboam son of Nebat. Dogs will eat those belonging to Baasha who die in the city, and birds will feed on those who die in the country.”

Moreover, the word of the Lord came through the prophet Jehu son of Hanani to Baasha and his house, because of all the evil he had done in the eyes of the Lord, arousing his anger by the things he did, becoming like the house of Jeroboam—and also because he destroyed it.

So Zimri destroyed the whole family of Baasha, in accordance with the word of the Lord spoken against Baasha through the prophet Jehu— because of all the sins Baasha and his son Elah had committed and had caused Israel to commit, so that they aroused the anger of the Lord, the God of Israel, by their worthless idols.

All Israel's kings were automatically bad by the writer's definition, though some were worse than others. After ruling for two years, Nadab is murdered by Baasha.

His successor, Elah, rules for two years before his assassination by Zimri.

Why?

When there is no the Lord and people turn away from the Lord, there is mas and destruction in this country.

The rules are changing soon, the writer recorded these kings of Israel as bad kings.

How?

Don't care about the rules of the world but care about the Lord who rules over all universal.
