Idols are powerless to deliver.  Ancient idols, created by craftsmen, were powerless to save, deliver or strengthen – the same is true of our modern, shiny, sophisticated idols.   Just as God formed us, so do craftsmen form idols – but these creators are human: they tire, get sick, get hungry & thirsty.  All idols are created out of created things that God gave mankind.  They used the wood to make a fire to bake their bread and then used what was left to fashion a “god” and then bow down and worship it, saying “deliver me!”  They cannot see that this is a created thing that they are looking for transcendence from.  Created things cannot provide transcendent answers.  On top of that, God has blinded them and shut up their hearts so that they cannot see the futility of their pursuit.
What do you delight in?  What do you look to for answers, satisfaction, identity, fulfillment?  These are your idols.  The heart will always worship something – either God or an idol.  Many times these are good things that we turn in to god things; things like marriage, family, faithful service, hard work or kid’s activities.  We teach our children what is worthy of worship and what they should seek to establish their true identity in life by what we will really trust in and what we really point them to – it may be athletics, relationships, morality, education or financial independence.  All of these things are good, but they are not designed to be our ultimate pursuit; they cannot hold the weight of our worship.  What “gospel” are you preaching to yourself and your children?  What do you say is worth all of your time, energy and pursuit?  What is your life ordered around?  This is what you really worship.  Is Jesus just one of many gods in your life?

“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).
