“The waters saw You, God; The waters saw You, they were in anguish; The ocean depths also trembled. The clouds poured out water; The skies sounded out; Your arrows flashed here and there.” – Psalm 77:16-17 (ESV)
There is a historical context for this Psalm of Asaph. Verses 19 and 20 indicate that it is regarding the crossing of the Red Sea during the Exodus. It is when we recall the time when the power of God intervened in our lives with a result that could only be the power and mercy of God. It is interesting that the psalmist attributes emotion to the waters and the depth of the Red Sea saying they were in anguish and trembling. It is vivid poetry applying imagination to what happened. Apart from the poetry of the description, the mention of rain and thunder and the quaking of the earth might surprise us. But it comes from the narrative in Exodus 14:24-25 where such sever weather effects were a part of the event in the way the pursuing Egyptians were mired in the sea bed and perished. Our God is a powerful God and able to do everything He choses to do without hinderance from the laws of nature. God is not bound by the natural laws as we are. Afterall the laws of physics and nature were created by God for our purpose.
