In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened.(Genesis 7:11) ESV
Did God build the fountains of the great deep for the purpose of flooding the Earth? If he did then he must have intended to flood it even before Adam and Eve sinned in the garden of Eden. That’s a problem.
The fountains of the great deep are one of those things which, if you think about it, might cause you to question whether or not God is truly good and benevolent. However, one rather fortunate outcome of developing a model of the interior of the Earth using systematic deduction is that we find that the fountains had a purpose which predates their use in the great flood of Noah. They were part of the creative process, they weren’t designed for a destructive purpose.
We already know that God is the power of gravity, and that his physical essence is the the deep from which creation was made. The power to take a ball of clay the size of Earth and shape it into a vessel capable of supporting life is a simple matter.
We refer back to the Hebrew word Rosh – רֹאשׁ, which we have used to identify Eden as the highest part of the dust of the earth. The word also means beginnings, as in, beginnings of streams.
In the context of the third day it refers to the point at which God metaphorically pressed his thumbs into the clay to begin shaping His vessel – the Earth.
The solid Earth was opened in one place, rosh, so that water could flow through the crust and down to a level where the crust and mantle separated from the core. As this separation occurred more water flowed into the Earth through the opening at rosh, until rosh was the first part of the Earth to emerge from the deep. It is the beginning of the dry land.
Once rosh emerged from the deep it was no longer possible for water to enter the Earth at rosh to continue the process. This meant that other channels through the crust and mantle were needed for the deep to flow through. These became known as the fountains of the great deep.
The fountains of the great deep are channels through the crust and mantle of the original Earth through which water drained into the great deep. They were later used to flood the Earth in the time of Noah.– Fountains of the Great Deep, definition
