A spirit of fire and a spirit of jedgment

Isaiah 4:2-6
In that day the Branch of the Lord will be beautiful and glorious, and the fruit of the land will be the pride and glory of the survivors in Israel.
Those who are left in Zion, who remain in Jerusalem, will be called holy, all who are recorded among the living in Jerusalem.
The Lord will wash away the filth of the women of Zion, cleanse the blood stains from Jerusalem by a spirit of judgment and a spirit of fire.
Three in one Spirit of judgement and one Spirit of fire.
The Lord will create over all of Mount Zion and over those who assemble there a cloud of smoke by day and a glow of flaming fire by night; over all the glory will be a canopy.
Why?
Isaiah (like Jesus) sees pride ad the root of so much wrong Evil has no place in the renewed city; only the few who are faithful to God will survive to enjoy it.
New growth shooting from the old roots; the community is to be reborn. Symbolized Jesus will be the new branch, a new relationship will be created between God and man.
Cloud in fire - the symbols of God's presence.
Faithful people are few but only those people can enjoy the glory and holy with the Lord.
There is a spirit of judgment and fire, one God, One Jesus and One Spirit to erase out guilt and sins. Don't be attracted away the focus away from God by others.
Spirit of fire in my heart that is a passion to the Lord, to love the people who needs the comfort and salvation from the Lord.
How?
Response the Lord with the enthusiasm to serve the Lord. With the spirit of fire and spirit of judgment.
