Charles H. Spurgeon on Psalms 107:29

He maketh the storm a calm. He reveals his power in the sudden and marvellous transformations which occur at his bidding. He commanded the storm and now he ordains a calm: God is in all natural phenomena, and we do well to recognise his working. So that the waves thereof are still. They bow in silence at his feet. Where huge billows leaped aloft there is scarce a ripple to be seen. When God makes peace it is peace indeed, the peace of God which passeth all understanding. He can in an instant change the condition of a man's mind, so that it shall seem an absolute miracle to him that he has passed so suddenly from hurricane to calm. O that the Lord would thus work in the reader, should his heart be storm beaten with outward troubles or inward fears. Lord, say the word and peace will come at once.
