The book of Isaiah is full of the glory of God, displays of the sinfulness of humanity, prophesies of Christ, and the promises of God. One of my favorite chapters is where Isaiah openly mocks the practice of idolatry in Israel. The commentary bleeds holy sarcasm. Pointed humor juts out everywhere.
Yet, before we jump too quickly jump into the “those idiots” mindset, Isaiah’s comments should cause us to pause and consider what created things we may be worshiping instead of the Creator. What do we think that we can’t live without? What do we think gives (or would give) us purpose and meaning in life? What do we spend the most time and/or money on every month? (For more on human idolatry, check out Timothy Keller’s Counterfeit Gods).
 All who fashion idols are nothing, and the things they delight in do not profit. Their witnesses neither see nor know, that they may be put to shame.  Who fashions a god or casts an idol that is profitable for nothing?  Behold, all his companions shall be put to shame, and the craftsmen are only human. Let them all assemble, let them stand forth. They shall be terrified; they shall be put to shame together.
 The ironsmith takes a cutting tool and works it over the coals. He fashions it with hammers and works it with his strong arm. He becomes hungry, and his strength fails; he drinks no water and is faint.  The carpenter stretches a line; he marks it out with a pencil. He shapes it with planes and marks it with a compass. He shapes it into the figure of a man, with the beauty of a man, to dwell in a house.  He cuts down cedars, or he chooses a cypress tree or an oak and lets it grow strong among the trees of the forest. He plants a cedar and the rain nourishes it.  Then it becomes fuel for a man. He takes a part of it and warms himself; he kindles a fire and bakes bread. Also he makes a god and worships it; he makes it an idol and falls down before it.  Half of it he burns in the fire. Over the half he eats meat; he roasts it and is satisfied. Also he warms himself and says, “Aha, I am warm, I have seen the fire!”  And the rest of it he makes into a god, his idol, and falls down to it and worships it. He prays to it and says, “Deliver me, for you are my god!”
 They know not, nor do they discern, for he has shut their eyes, so that they cannot see, and their hearts, so that they cannot understand.  No one considers, nor is there knowledge or discernment to say, “Half of it I burned in the fire; I also baked bread on its coals; I roasted meat and have eaten. And shall I make the rest of it an abomination? Shall I fall down before a block of wood?”  He feeds on ashes; a deluded heart has led him astray, and he cannot deliver himself or say, “Is there not a lie in my right hand?”
(Isaiah 44:9-20 ESV)
