Acknowledge that the Lord is real sovereign Lord over everything.

Daniel 4:1-27
King Nebuchadnezzar to the peoples, nations and men of every language, who live in all the world: May you prosper greatly! It is my pleasure to tell you about the miraculous signs and wonders that the Most High God has performed for me. How great are his signs, how mighty his wonders! His kingdom is an eternal kingdom; his dominion endures from generation to generation.
Nebuchadnezzar had another dream about a tree and be cut down when he was in his palace, contented and prosperous, but let the stump and its root, bound with iron and bronze, remain in the ground, in the grass of the field. He received message from heaven.
The decision is announced by messengers, the holy ones declare the verdict, so that the living may know that the Most high is sovereign over the kingdoms of men and gives them to anyone he wishes and sets over them the lowliest of men.
Daniel interprets the dream for king. Daniel advised king: renounce his sins by doing what is right, and his wickedness by being kind to the oppressed. It may be that then his prosperity will continue.
Why?
Nebuchadnezzar himself authenticates this extraordinary story. Perhaps sensing that this dream is against himself, he does not turn to Daniel straight away.
It is clear from Daniel's dismay that he does not wish the king ill.
Seven times: The length of time here as elsewhere in Daniel is unspecified. It was a definite, limited period of time fixed by God. (Seven years, is also possible)
King Nebuchadnezzar was proud in his achievement, so the Lord gave him a dream to warn him. King knew it, but he still proud in himself.
The most high, the Lord, sovereign over the kingdoms of men. No one can do what he wants to do, the Lord is sovereign Lord, his dominion endures for ever. No any kingdom on earth could be exist for ever.
When a man is living in situation of contented and prosperous, it is easy to proud.
How?
The love of the Lord is abundant, if renounce his sin by doing what is right and by being kind to oppressed, it may be the wrap of the God won't come.
Acknowledge that the Lord is real sovereign Lord over everything.
