In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. (Genesis 1:1-2, KJV)
To understand how the flood happened, we need to go to the beginning of life on earth.
In the Hebrew, it is written as:
The King James Version of the Bible translated the above as:
And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. (Genesis 1:2)
Now if we take the original text and apply a mechanical translation to the verse, we come up with:
and~ the~ Land she~ had~ Exist Confusion and~ Unfilled and~ Darkness Upon Face~ s Deep.sea and~ Wind “Elohiym [Powers]” much~ Flutter~ ing(fs) Upon Face~ s the~ Water~ s2
Which is then interpreted as:
and the land had existed in confusion and was unfilled and darkness was upon the face of the deep sea and the wind of “Elohiym [Powers]” was much fluttering upon the face of the water,
This in no way takes away from the King James translation, but rather builds on it and makes clear the vagueness regarding the "face of the deep" and "face of the waters". This also identifies that sometime before the creation of LIFE upon the earth, the earth existed as a "bottomless pit" (Revelation 20:1) or “a land not inhabited” (Leviticus 16:22). The difference is that the earth was covered in water and had thick vaporous atmosphere but was completely void and dead of life; similar to what we see with other gas planets in our own solar system.
When God came to this world; in our beginning, not the beginning of the universe (as these are two different time stamps), one of His actions was to separate the waters from the waters and to let the dry land appear. (Genesis 1:6&10)
And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters... And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good. (Genesis 1:6&10)
Job 22:15-17 tells us why the flood happened and how the flood happened. It is also a warning for us today, where more and more are rejecting the spirit of God.
The world in the time of Noah, literally told God to “Depart from us.” (Job 22:17)
Hast thou marked the old way which wicked men have trodden? Which were cut down out of time, whose foundation was overflown with a flood: Which said unto God, Depart from us: and what can the Almighty do for them? (Job 22:15-17, KJV
Another translation states it as:
Will you keep to the old way which wicked men have trod? They were snatched away before their time; their foundation was washed away. They said to God, ‘Depart from us,’ and ‘What can the Almighty do to us?’ (Job 22:15-17, RSV)
So, giving man up to his own will (as the wrath of God is expressed in Romans 1; see also the article on Anger and Wrath Together), God’s presence was removed from the Earth; and what happened? Without the protective, creative and redemptive power of God which holds all things together (Col 1:17; Wisdom 1:7), the world went back to its natural state before creation:
A rock, covered in water, floating in space. As it is expressed in Genesis 1:2.
And the earth was without form, and void; and darkness was upon the face of the deep... (Genesis 1:2, KJV)
The wicked often go unpunished and point to the future saying their sins are saved up for the future (Job 21), that God has done nothing for them and there is nothing that God will do to them because of their sin; they tell God to "Depart from us, We do not desire the knowledge of thy ways." (Job 21:14). So, God leaves them to their own will and that by God’s presence leaving the earth, He brings forth waters to cover the earth as a result of His lack of presense. He didn't hover over the earth and bring the waters to kill all life. It was the demand of the people, in their rejection of Him that He left and the results of Him leaving brought the earth back to it's lifeless-origional state. That’s why God warned Noah that He was going to bring a flood.
For behold, I will bring a flood of waters upon the earth, to destroy all flesh in which is the breath of life from under heaven; everything that is on the earth shall die. (Genesis 6:17)
This is why and how the flood happened. This is also a warning to us in these last days of turmoil, hatred and bigotry; as the world continues to reject the Spirit of God, God will send His Son to receive of His own (Christ is our Ark for this time as the Ark represented Christ at that time - see Maranatha Media Newsletter Feb 8, 2018) and REMOVE, again, His presence from the Earth, fully, except that the one who is bound to the earth may walk upon it for a thousand years; alone, with no one to tempt and with the results of his sin to look upon. A lifeless dead planet.
