A Quranic note on thinking oneself invincible

In a time when Pharoah proclaimed:

﴾ مَا عَلِمْتُ لَكُمْ مِنْ إِلَهٍ غَيْرِي ﴿
I have not known you to have a god other than me (28:38)

and when Pharaoh was...well....being a Pharaoh 

   إِنَّ فِرۡعَوۡنَ عَلَا فِى ٱلۡأَرۡضِ وَجَعَلَ أَهۡلَهَا شِيَعً۬ا يَسۡتَضۡعِفُ طَآٮِٕفَةً۬ مِّنۡہُمۡ يُذَبِّحُ أَبۡنَآءَهُمۡ وَيَسۡتَحۡىِۦ  نِسَآءَهُمۡ‌ۚ إِنَّهُ ۥ كَانَ مِنَ ٱلۡمُفۡسِدِين 
"Indeed Pharaoh exalted himself in the land and made its people into factions, oppressing a sector among them, slaughtering their [newborn] sons and keeping their females alive. Indeed, he was of the corrupters." (28:4)

God told Moses' mother, after she realized she gave birth to a son, to trust in Him and put Moses in the river....

﴾وَأَوْحَيْنَا إِلَى أُمِّ مُوسَى أَنْ أَرْضِعِيهِ فَإِذَا خِفْتِ عَلَيْهِ فَأَلْقِيهِ فِي الْيَمِّ وَلَا تَخَافِي وَلَا تَحْزَنِي إِنَّا رَادُّوهُ إِلَيْكِ وَجَاعِلُوهُ مِنَ الْمُرْسَلِينَ ﴿ 
And We inspired to the mother of Moses, "Suckle him; but when you fear for him, cast him into the river and do not fear and do not grieve. Indeed, We will return him to you and will make him [one] of the messengers." (28:7)

Hold on!
This doesn't make sense? To rescue your son from certain death by putting him in a river were death seems inevitable? She relied on God however and did what she was told. 

Back to the story..

The river currents took Moses to the doorsteps of Pharaoh's palace. Yup, right to his doorsteps but Pharaoh's wife saw the baby, fell in love with him and spared his life

﴾لَا تَقْتُلُوهُ عَسَى أَنْ يَنْفَعَنَا أَوْ نَتَّخِذَهُ وَلَدًا﴿ 
"Do not kill him; perhaps he may benefit us, or we may adopt him as a son." (28:9)

And Moses now is in the hands of the same person seeking to kill him yet no harm can get to him!
Moses grew up in Pharaoh's home, right in front of Pharaoh's eyes and under Pharaoh's protection.  And the rest, as they say, is history. (Think parting of the sea and all)

What's the moral of this story?

To me, there are many. But what stands out most is the frailty and fragility of those who think themselves, or we at times consider, invincible.

Pharaoh thought himself a God; a powerful, seemingly untouchable and magnanimous God. His arrogance led him to think himself invincible yet his demise came on the hands of the very person he sought to destroy. He couldn't stop the inevitable even when it was in his grasp.

So what do we think ourselves all high and mighty for?
