Charles H. Spurgeon on Psalms 136:4

To him who alone doeth great wonders. Jehovah is the great Thaumaturge, the unrivalled Wonder worker. None can be likened unto him, he is alone in wonderland, the Creator and Worker of true marvels, compared with which all other remarkable things are as child's play. His works are all great in wonder even when they are not great in size; in fact, in the minute objects of the microscope we behold as great wonders as even the telescope can reveal. All the works of his unrivalled skill are wrought by him alone and unaided, and to him, therefore, must be undivided honour. None of the gods or the lords helped Jehovah in creation, or in the redemption of his people: his own right hand and his holy arm have wrought for him these great deeds. What have the gods of the heathen done? If the question be settled by doings, Jehovah is indeed "alone." It is exceedingly wonderful that men should worship gods who can do nothing, and forget the Lord who alone doeth great wonders. Even when the Lord uses men as his instruments, yet the wonder of the work is his alone; therefore let us not trust in men, or idolize them, or tremble before them. Praise is to be rendered to Jehovah, for his mercy endureth for ever. The mercy of the wonder is the wonder of the mercy; and the enduring nature of that mercy is the central wonder of that wonder. The Lord causes us often to sit down in amazement as we see what his mercy has wrought out and prepared for us: "wonders of grace to God belong", yea, great wonders and unsearchable. Oh the depth! Glory be to his name world without end!

Doing wondrous deeds alone,

Mercy sits upon his throne.
