Charles H. Spurgeon on Psalms 89:9

Thou rulest the raging of the sea. Always, even in the hour of ocean's maddest fury, the Lord controls it. At the Red Sea the foaming billows saw their God and stood upright in awe. When the waves thereof arise, thou stillest them. None else can do this; to attempt it would be madness, but the Lord's "hush" silences the boisterous storm. So did the Lord's Anointed calm the storms of Galilee, for he is Lord of all; so also does the great Ruler of Providence evermore govern the fickle wills of men, and quiet the tumults of the people. As a mother stills her babe to sleep, so the Lord calms the fury of the sea, the anger of men, the tempest of adversity, the despair of the soul, and the rage of hell. "The Lord sitteth upon the floods; yea, the Lord sitteth King for ever", and in all his ruling and over ruling he has respect unto his covenant; therefore, although our house be not so with God as our hearts would wish, yet we will rejoice in his covenant ordered in all things and sure, and delight in him as all our salvation and all our desire.
