Begin at my sanctuary

Ezekiel 9:1-11
Then the Lord called to the man clothed in linen who had the writing kit at his side  and said to him,“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.” 
Follow him through the city and kill, without showing pity or compassion. Slaughter the old men, the young men and women, the mothers and children,  but do not touch anyone who has the mark. Begin at my sanctuary.”
Contrary to popular belief, God both sees and judges. Only those who grieve for the loss of the true faith will be spared.
But God spared the people who were lam and grieve over all the detestable things that are done in it.
So God is fair and with mercy to his people, God blessed those who kept away from detestable things.
God is righteousness and love us with mercy, God's judgment will come from the sanctuary, from the  elder and his servants - ministers, Christians.
How?
Fear the Lord and away from any detestable things. For the righteousness of the Lord.
