I have done nothing in it without cause

Ezekiel 14:12-23
For this is what the Sovereign Lord says: How much worse will it be when I send against Jerusalem my four dreadful judgments—sword and famine and wild beasts and plague—to kill its men and their animals!
As surely as I live, declares the Sovereign Lord, even if Noah, Daniel and Job were in it, they could save neither son nor daughter. They would save only themselves by their righteousness.
Yet there will be some survivors—sons and daughters who will be brought out of it. They will come to you. You will be consoled when you see their conduct and their actions, for you will know that I have done nothing in it without cause, declares the Sovereign Lord.
But at this point in time not even Noah or Job could save anyone but themselves.
This judgment represent the worst fears of ancient peoples.
Why?
These were severe disaster to Jerusalem, for God's dreadful judgments, for their own conducts.
Yes, God's action has done nothing in it without cause. 
Even Noah, Daniel and Job were in it, they could save themselves only, they could not save their children or relatives.
God is right and God's way is the best way, God has done nothing it without cause. Trust in the Lord, He is my shepherd.
How?
Fear the Lord for God's judgment is terrible, God has given us the chances and time let us repent and turn to Jesus Christ.
