Nothing will be left

Isaiah 39:1-8
Envoys from Babylon, Hezekiah received the envoys gladly and showed them what was in his storehouses. There was nothing in his palace or in all his kingdom that Hezekiah did not show them.
Then Isaiah said to Hezekiah, "Here the word of the Lord Almighty: The time will surely come when everything in your palace, and all that your predecessors have stored up until this day, will be carried off to Babylon. Nothing will be left, says the Lord.
"The word of the Lord you have spoken is good," Hezekiah replied. For he though, "There will be peace and security in my lifetime."
Hezekiah's illness and the embassy from Babylon probably preceded the siege. The events may have been reversed here to provide a lead-in to the following chapters, which focus on Babylon as the world power in later became.
'Peace in my time' was Hezekiah's reaction to the terrible prediction of conquest and captivity. Isaiah could draw no comfort from the thought.
Why?
When Hezekiah recovery from illness, he forgot what is the humble, all he has are God's mercy and grace. It is not the credit of him. So the Lord let Isaiah said the result of his wealth and posses will be carried to Babylon.
The word Hezekiah replied so not good, he considered his own life only. He did not care the future of Judah. It is selfish mind so Isaiah did not comfort from the though. Hezekiah may return to the Lord.
How?
A man is easy forget the mercy and grace from the Lord when he is safe and joy. Be alert! Always keeping humble before the Lord and honor the name of the Lord.
