Charles H. Spurgeon on Psalms 94:9

He that planted the ear, shall he not hear? He fashioned that marvellous organ, and fixed it in the most convenient place near to the brain, and is he deaf himself? Is he capable of such design and invention, and yet can he not discern what is done in the world which he made? He made you hear, can he not himself hear? Unanswerable question! It overwhelms the sceptic, and covers him with confusion. He that formed the eye, shall he not see? He gives us vision; is it conceivable that he has no sight himself? With skilful hand he fashioned the optic nerve, and the eyeball, and all its curious mechanism, and it surpasses all conception that he can himself be unable to observe the doings of his creatures. If there be a God, he must be a personal intelligent being, and no limit can be set to his knowledge.
