He removed the detestable idols from the whole land, so the Lord gave them rest on every side.

2 Chronicles 15:1-19
The Spirit of God came on Azariah son of Oded.  He went out to meet Asa and said to him, “Listen to me, Asa and all Judah and Benjamin. The Lord is with you when you are with him. If you seek him, he will be found by you, but if you forsake him, he will forsake you.
When Asa heard these words and the prophecy of Azariah son of Oded the prophet, he took courage. He removed the detestable idols from the whole land of Judah and Benjamin and from the towns he had captured in the hills of Ephraim. He repaired the altar of the Lord that was in front of the portico of the Lord’s temple.
They assembled at Jerusalem in the third month of the fifteenth year of Asa’s reign. They took an oath to the Lord with loud acclamation, with shouting and with trumpets and horns. All Judah rejoiced about the oath because they had sworn it wholeheartedly. They sought God eagerly, and he was found by them. So the Lord gave them rest on every side.
King Asa also deposed his grandmother Maakah from her position as queen mother, because she had made a repulsive image for the worship of Asherah. Asa cut it down, broke it up and burned it in the Kidron Valley.
Azariah is mentioned only here in the Old Testament. His prophecy is the spur that sets As's reforms in motion.
Loyal men from the two northern tribes migrated to Judah. But Simeon's territory had always been in the south, and the bribe had been assimilated long ago by Judah.
Why?
Asa listened to the word of God from Azariah and gave him the courage to remove the detestable idols from the whole land of Judah and Benjamin and all his territory.
Only God can give us rest and peace in the world.
The family of the king is the source of idols make in the time of Solomon. Asa has the power to deposed his grandmother Maakah from her position as queen mother is a great activity to remove idols.
Wholehearted worship to the Lord should be with action, such as remove the idols from our hearts.

丘壇未廢去，已經許久了。百姓沒有律法的教導，以致王熱心，百姓卻無知。可能從士師時代開始。即好久沒有聽道了，很久沒有讀經了。
7000隻羊雖然沒有所羅門時那麼多，但是也是相當大的量。百姓都一起來立約。
亞比雅的媽媽所立的柱像拆掉、廢掉太后位子。做門徒要以耶穌為標竿。事物的關係，甚至親情的關係，都是以耶穌基督為準。重新整隊的參考點中央伍。
亞撒王改革從自己做起。
改革留下尾巴。即丘壇沒有廢去的遺憾。很多人都參加了，但是不見得每個人持續這個感動而有行動。或者說有的感動是做樣子。愛主不是做樣子，愛主要盡心、盡性、盡意、盡力。為什麼要分四個部份，因為神很容易為自己保留一點世界上的東西、情慾。所以提醒我們要小心。

How?
Let's removed the detestable idols from my heart, only the Lord is my king in my heart!
