There are certain themes in Scripture that tend to beat you over the head with their persistence. Idolatry is one of those. It’s such a prominent theme in Scripture that some have said it is the central theme of the entire Bible. And when it comes to idolatry, we humans are endlessly creative. As John Calvin said, “The heart of man is a perpetual factory of idols.”Give us the chance, and we’ll replace God with any and every object, person, ideal, or dream.
Most modern people don’t quite get the Bible’s obsession with idolatry. We think of idolatry as an ancient problem for backwards people who bowed down to statues, not a relevant one for sophisticated folks like us. But we aren’t beyond idolatry. We simply dress it up in different clothes.
Acts 19 gives us 5 insights into the reality of idolatry for us today:
1. An idol is anything that promises a life of security and joy apart from God.
In Acts 19, Artemis is described as the “protector” and “prosperer” of Ephesus. With her, the Ephesians believed, they were guaranteed security and joy. This false hope is precisely what makes an idol an idol. Idols are not usually bad things, but good things that have become ultimate things—things you believe guarantee you joy and security.
What is that in your life? About what do you think, “As long as I have this, I’ll have happy”?
What do you so desperately need that you can’t imagine a fulfilled life without it?
What makes these idols so dangerous is that they are nearly always good things. I have seen the good of desiring marriage become a false god. I’ve seen the good of wanting to provide become the idol of always needing to achieve one more financial benchmark. The problem isn’t the money or the marriage. The problem comes when we trust in those things to satisfy.
2. Idols engage the deepest emotions in our hearts.
When idols are challenged, people get violent. That’s what happens in Acts 19, when Artemis’ prowess is threatened. And it’s what happens in our lives when something we love is threatened, because many of our deepest emotions are connected to idols. Some of my deepest emotions are connected to worshipping the idol of success.
What is that in your life? About what do you think, “If I ever lost this, I’d never survive”? What possible loss makes you not only frightened, butdespairing?
The irony here is that idolizing something ultimately keeps you from being able to enjoy it at all. You panic and fret about losing something so vital that you can never rest. For instance, many of the wealthiest people are the most paranoid about their money. Gaining more of an idol only heightens that sense of fear, because nothing other than God can sustain the weight of your soul.
3. Idols need to be protected.
One of the craftsmen in Ephesus, Demetrius, was making a fortune on Artemis statues, coffee mugs, and bobble-head dolls. He wasn’t about to stand idly by while Paul undermined his entire financial enterprise with his “Gods made with hands are not really gods” message. So he gathered up an impromptu group of thugs to force Paul out of town.
Don’t miss the humor in this: Artemis was the protector of Ephesus. Yet when Demetrius’ skin was in the game—his cash flow—he immediately jumped up to defend her. That’s the absurdity of idolatry: what is supposed to protect usbecomes something we fiercely protect.
What is that in your life? What do you feel obsessive about protecting in your life?
Charles Spurgeon said the Word of God is like a caged lion. If someone threatens the lion, you don’t have to step in and defend the lion; you just let it loose and it will protect itself. The God of the Word can protect himself, but our false gods always need to be protected.
4. Idols demand sacrifices to keep them happy.
The whole system in Ephesus was built on appeasing Artemis and keeping her happy. That was no accident: idols will always make you sacrifice for them. If business is your idol, you’ll sacrifice your integrity to climb the ladder of success. If acceptance is your idol, you’ll sacrifice your honesty and lie to get affirmation. If romance is your idol, you’ll walk out on your spouse as soon as the “spark” seems to fade.
But an idol is like a fire. It never says, “That’s enough.” Instead, it just keeps asking for more. The altar of idolatry is terrifyingly insatiable: the more you sacrifice for an idol, the more it will demand.
What is that in your life?What part of yourself have you sacrificed on the altar of an idol? Where do you feel that “pull” to keep cutting corners or making excuses? Don’t fool yourself into thinking that this sacrifice will be the last one.
5. The gospel overcomes our idolatry.
The idol of money says to us, “If you don’t do enough to obtain me, I’ll make you miserable.” The idol of family says, “If you lose me, life won’t be worth living.” The idol of comfort says, again and again, “Sacrifice your honesty, your integrity, your closest relationships, for me.”
Idols are harsh taskmasters. If you fail them, they make you pay. But in the gospel Jesus says to us, “You did fail me. But instead of destroying you, I’ll let myself be destroyed for you. Instead of demanding a sacrifice, I will become a sacrifice for you.” In Jesus, unlike idols, we find the only God that—when we obtain him—will satisfy us, and—when we fail him—will forgive us.
 Cf. Jewish scholar Moshe Halbertal, Idolatry, in which Halbertal claims that the story of the Old Testament is primarily that of the conflict between the true God and all false challengers.
