All those who make idols are worthless, and the gods they prize so highly are useless. Those who worship these gods are blind and ignorant - and they will be disgraced.
It does no good to make a metal image to worship as a god!
Everyone who worships it will be humiliated. The people who make idols are human beings and nothing more. Let them come and stand trial - they will be terrified and will suffer disgrace.
The metalworker takes a piece of metal and works with it over a fire. His strong arm swings a hammer to pound the metal into shape. As he works, he gets hungry, thirsty, and tired.
The carpenter measures the wood. He outlines a figure with chalk, carves it out with his tools, and makes it in the form of a man, a handsome human figure, to be placed in his house.
He might cut down cedars to use, or choose oak or cypress wood from the forest. Or he might plant a laurel tree and wait for the rain to make it grow.
A person uses part of a tree for fuel and part of it for making an idol. With one part he builds a fire to warm himself and bake bread; with the other part he makes a god and worships it. 1
References for Isaiah 44:15
With some of the wood he makes a fire; he roasts meat, eats it, and is satisfied. He warms himself and says, "How nice and warm! What a beautiful fire!"
The rest of the wood he makes into an idol, and then he bows down and worships it. He prays to it and says, "You are my god - save me!"
Such people are too stupid to know what they are doing. They close their eyes and their minds to the truth.
The maker of idols hasn't the wit or the sense to say, "Some of the wood I burned up. I baked some bread on the coals, and I roasted meat and ate it. And the rest of the wood I made into an idol. Here I am bowing down to a block of wood!"
It makes as much sense as eating ashes. His foolish ideas have so misled him that he is beyond help. He won't admit to himself that the idol he holds in his hand is not a god at all.
