Charles H. Spurgeon on Psalms 135:18

They that make them are like unto them. they are as blockish, as senseless, as stupid as the gods they have made, and, like them they are the objects of divine abhorrence, and shall be broken in pieces in due time. So is every one that trusteth in them. The idol worshippers are as bad as the idol makers; for if there were none to worship, there would be no market for the degrading manufacture. Idolaters are spiritually dead, they are the mere images of men, their best being is gone, they are not what they seem. Their mouths do not really pray, their eyes see not the truth, their ears hear not the voice of the Lord, and the life of God is not in them. Those who believe in their own inventions in religion betray great folly, and an utter absence of the quickening Spirit. Gracious men can see the absurdity of forsaking the true God and setting up rivals in his place; but those who perpetrate this crime think not so: on the contrary, they pride themselves upon their great wisdom, and boast of "advanced thought" and "modern culture." Others there are who believe in a baptismal regeneration which does not renew the nature, and they make members of Christ and children of God who have none of the spirit of Christ, or the signs of adoption. May we be saved from such mimicry of divine work lest we also become like our idols.
