Charles H. Spurgeon on Psalms 104:9

Thou hast set a bound that they may not pass over; that they turn not again to cover the earth. That bound has once been passed, but it shall never be so again. The deluge was caused by the suspension of the divine mandate which held the floods in check: they knew their old supremacy, and hastened to reassert it, but now the covenant promise for ever prevents a return of that carnival of waters, that revolt of the waves: ought we not rather to call it that impetuous rush of the indignant floods to avenge the injured honour of their King, whom men had offended? Jehovah's word bounds the ocean, using only a narrow belt of sand to confine it to its own limits: that apparently feeble restraint answers every purpose, for the sea is obedient as a little child to the bidding of its Maker. Destruction lies asleep in the bed of the ocean, and though our sins might well arouse it, yet are its bands made strong by covenant mercy, so that it cannot break loose again upon the guilty sons of men.
