Arousing God's anger

2 Kings 21:1-26
Manasseh did evil in the eyes of the Lord,following the detestable practices of nations the Lord had driven out before the Israelites.
I will stretch out over Jerusalem the measuring line used against Samaria and the plumb line used against the house of Ahab. I will wipe out Jerusalem as one wipes a dish, wiping it and turning it upside down. I will forsake the remnant of my inheritance and give them into the hands of enemies. They will be looted and plundered by all their enemies.
Amon was twenty-two years old when he became king, and he reigned in Jerusalem two years. He did evil in the eyes of the Lord, as his father Manasseh had done.
Why?
Manasseh did the evil before the Lord,even his father was obey God's word. This is the destination of God for many his forefathers,like Ahab, did not obey the commandment of the Lord. It is the consequence of the Israelites made covenant with the Lord.
Peace and prosperity may lead people forget that it is the blessing of the Lord.
How?
God's word is existing forever. His grace and judgement are existing forever.
