The Mark of righteous men

Ezekiel 9:1-11
The Lord order the guards with weapon in his hand and go through the city and kill, without showing pity or compassion.
Before the slaughter, the Lord asked them was a man clothed in linen who had a writing kit at his side. They go throughout the city of Jerusalem and put a mark on the foreheads of those who grieve and lament over all the detestable things that are done in it. - The Lord save the people who are righteousness.
Slaughter begin at  my sanctuary, but do not touch anyone who has the mark, So they began with the elders who were in front of the temple.
Ezekiel prayed to the Lord, God said to him 'The sin of the house of Israel and Judah is exceedingly great; the land is full of bloodshed and the city is full of injustice.' They say, 'The Lord has forsaken the land; the Lord does not see.'
Why?
The Lord let Ezekiel see the vision of the loss of Jerusalem and the evil will be clear by the hands of the Lord.
Only those who grieve for the loss of the true faith will be spared.
A Mark: Jeremiah, Baruch and the foreigner, Ebed-meleh, were among those 'marked' to be spared. In Revelation those true to God are marked, and so are those who sell out to the forces of evil. The mark here is the last letter of the Hebrew alphabet, taw, written as a cross in the oldest script.
Idolatry has been the chief sin so far. Here it is clear that the most basic laws have been broken.
Elders in the temple were justified first, so the leaders of the church shell aware of this. Doing right, or the judge of the Lord comes upon them first. The leader of church takes responsibility of Shepherd God's people.
When God's wrath are broken out, no one can stop it.
How?
No matter is living among any city, don't follow the detestable thing and do what is right and grieve for the loss faith will be spared.
