Psalms 104:5-9 (ESV)
He set the earth on its foundations,
so that it should never be moved.
You covered it with the deep as with a garment;
the waters stood above the mountains.
At your rebuke they fled;
at the sound of your thunder they took to flight.
The mountains rose, the valleys sank down
to the place that you appointed for them.
You set a boundary that they may not pass,
so that they might not again cover the earth.
The above passage speaks to how uncontrollable the waters and seas are, but the passage below speaks to how God controls them (only He can) to use them as source for His creation. What was a chaotic mess in front of God, before creation (Genesis 1), has become a tool for God, after creation. The power of these two passages teaches us that there is nothing before God that can’t be turned into a blessing by God.
Psalm 104:10-13
You make springs gush forth in the valleys;
they flow between the hills;
they give drink to every beast of the field;
the wild donkeys quench their thirst.
Beside them the birds of the heavens dwell;
they sing among the branches.
From your lofty abode you water the mountains;
the earth is satisfied with the fruit of your work.
