Charles H. Spurgeon on Psalms 89:9

Thou rulest. Here under a figure taken from God's providential government, we have an exhibition of the power of God in defeating the efforts of the enemies of his Church. An instance of this, in the literal sense, we have in the appeasing of the storm by our Lord. "And he arose, and rebuked the wind, and said unto the sea, Peace, be still. And the wind ceased, and there was a great calm." Here we see that God reigns over the sea immediately, and alters or modifies the arrangements of nature according to his sovereign pleasure. That which Jesus did on one occasion is constantly done by the God of providence. He has not left the ocean to be disturbed at random by the winds, nor to be kept in peace by the laws of nature. He rules the raging of the sea. He raises the waves, and he stilleth them. This exhibits a continually working providence. And what he does in providence he does also in his kingdom of grace. He suffers the fury of the enemy to swell against his cause, but he stills it at his pleasure. —Alexander Carson.
