God is always involved in the operations of the universe. He is the one who controls everything, including nature. Is it not God Himself who stirs up the sea? (Isaiah 51:14)
Naturalists constantly seek to explain how the universe can operate without God, but such a search is pointless. The structure of microscopic atomic particles will never fully be able to explain how the universe operates. Oh how the world loves to peer into their microscopes in order to invent reasons to continue in rebellion! Oh how the world loves to come up with theory after theory while ignoring the Creator— while ignoring the very Person who is before all things and in whom all things hold together! (Colossians 1:17)
It is impossible. Read that again: impossible to fully grasp Genesis 8:1 without stripping away unbiblical naturalistic philosophies. And so, with perhaps a better mindset, read Genesis 8:1 again:
But God remembered Noah and all the beasts and all the cattle that were with him in the ark; and God caused a wind to pass over the earth, and the water subsided.In order that God might fulfill His purposes, He caused a wind to pass over the earth. Perhaps angels were involved in the process of releasing the wind, or perhaps God simply sent the wind Himself. Regardless, God achieved what He desired: the water subsided. And why did God want the flood to subside? Why did God once again want to gather the water into one place (Genesis 1:9)? For this reason: God remembered Noah. In the midst of His wrath, God remembered mercy (Habakkuk 3:2).
Imagine the situation that Noah was in right before God caused the wind to blow: For 150 days, Noah had lived on the ark. And the world, from Noah's perspective, must have appeared to be in a hopeless condition. Noah had not seen any land for over 110 days! And gradually, perhaps doubts began to enter Noah's mind. Would the water ever depart? Would they ever walk on land again? Had God... forgotten them?
