Doom for the mountains of Israel

Ezekiel 6:1-14
Wherever you live, the towns will be laid waste and the high places demolished, so that your altars will be laid waste and devastated, your idols smashed and ruined, your incense altars broken down, and what you have made wiped out. Your people will fall slain among you, and you will know that I am the Lord.
And they will know that I am the Lord; I did not threaten in vain to bring this calamity on them.
This is what the Sovereign Lord says: Strike your hands together and stamp your feet and cry out “Alas!” because of all the wicked and detestable practises of the people of Israel, for they will fall by the sword, famine and plague.
And I will stretch out my hand against them and make the land a desolate waste from the desert to Diblah—wherever they live. Then they will know that I am the Lord.
The acted message us reinforced by the spoken word. The people's flagrant idolatry is about to bring destruction upon them judgment from which there is no escape. Then they will know that the Lord is God indeed. Terrible, total calamity is be falling the land.
Why?
People are easy forget the grace of the Lord and even warning from the word they believed they can make it so they are doing the same things same wicked matter the make their own idols. Until all of their idols, altars are broken down, there is no way to go then they come to the Lord if God have mercy on them.
All of the mountain are beauty but Israelite make altar and idols on the hills, so God let sword and demolish come upon their land. totally calamity is be falling the land.
How?
Listen to the word of the Lord and humble myself, meditate the word of God in my heart, get away form any evil things.
