Summary: Man is always quick to forget that he does not have the supreme authority over himself. There is a God outside of man who rules over the affair of man.
Regardless of genealogy or demography, every human shares something in common and it is the fact that we all came from dust and to dust shall we all return. Everyone came empty and shall someday return empty. Class notwithstanding, all men are same and nothing (Psalm 62:9). Psalm 103:15-16 also describes man as flower that flourishes for a season and it is no more. What is man but mere mortal?
There are men whose sense of reasoning is beclouded by their achievement, possession, influence, skills, knowledge, etc and so play God. They soon forget that man will always be man irrespective of the prevailing circumstances. Man is always quick to forget that he does not have the supreme authority over himself. There is a God outside of man who rules over the affair of man.
God is God and His sovereignty is absolute and undebatable. After his sheer display of arrogance and subsequent adventure as a beast in the wilderness for seven straight years, King Nebuchaddnezzar returned with the understanding that there is a King Most High who sets up kings and pulls down others at will and He is answerable to no one.
Just as man does not have rule over himself, he does not have anything that he has not received. It therefore amounts to cheer arrogance when one assumes the position of God over himself or others because of what he think he has been able to achieve or the edge he has over others. Irrespective of who you think you are or what you think you have or who/what you pledge allegiance to, you are still a mortal and the handiwork of God.
"Arise, O LORD; let not man prevail: let the heathen be judged in thy sight. Put them in fear, O LORD: that the nations may know themselves to be but men (Psalm 9:19-20)."
When the Almighty God decides to show what man is really worth, the story is always pathetic. Pharaoh, the king of Egypt lost almost everything trying to perpetuate himself as a taskmaster over the children of Israel. Nebuchaddnezzar, the king over several provinces lost his understanding and became a beast. Herod, the king who accepted the accolade of having the voice of God became as meat for maggots to feed on.
Our God is plenteous in mercy and His love is unimaginable yet it is a terrible thing to experience the wrath of Him that sits on the throne. He detests pride and the proud with every fibre in Him (Pro 29:23; Jam 4:6; 1Pet 5:5). No matter who you are or what level you have attained, always remember that you are mere mortal and there is a Supreme Being who is in charge of all things including you.
