All life stopped, All thoughts were captured, all wits dismembered, all hopes stalled, all dreams stopped and they work to the reality that if GOD left humanity, there was going to be a great depreciation and consequently, a lack of cohesion to life.
GOD can use a baby's smile to heal the broken-hearted, a child’s walk to save the misdirected, a woman's wit, a man's senses, a buzzing fly, a moving train, a lost coin, a manifold stack of cards.
This Hail, the eighth sign from GOD, was greater than anything Egypt had seen. It was hail of ice and darts of fire. Only the finger of GOD could fight men in their own conjoined battles and win beyond interpretation.
This is me speaking freely to you, Chi. It is shocking and way beyond me honestly. Here, if this was a game of chess, GOD had HIS checkmate move three plagues ago yet HE insisted that it was not enough by hardening the heart of Pharaoh.
This is also why GOD is eager to get Israel free because no child of GOD is slave to man, men or the wits and ways of men. In this regard, GOD gives Pharaoh another answer of faith. Separation.
So for Pharaoh, it was GOD's way of stretching his doubt to its limits; how far could his query of GOD go? However, Pharaoh did believe. In the moment of torment, in the evidence that these things were by the hand of GOD, Pharaoh believed.
Whether, we can analyse the reason why HE does what HE does, it is certain that GOD is in the business of stunning us with the impossible to do what is made possible only by HIM.
One reason why GOD doesn’t make sense to humans who are armed with their worldview of disbelief and doubt is because there is an answer of pride to the question of what the reason of existence is.
The plagues upon Egypt were GOD's way of letting Pharaoh know that there was more that he did not know and more than he did know.
