Much of my free time in the last few weeks has been spent preparing a sermon on the subject of idolatry, which I am preaching tomorrow as part of a series my church is doing on the Ten Commandments.

I wanted to include some reflection on how we can examine our hearts to see if we are guilty of idolatry. One way of looking at this is to take John Piper’s maxim, “your pleasure is the measure of your treasure”. If something brings you great joy, it reveals that you value that thing highly.

But I began to wonder whether the reverse is equally revealing. What are the things that make me grumpy, irritable, miserable, depressed, or angry? Often it is because I have been deprived of an idol or an idol has let me down.

Here are some examples…

  • A football supporter kicks a chair across the room in anger as his team concedes a last minute goal, yet again.
  • A woman lives under a cloud of depression because her dress size is one bigger than this time last year.
  • A teenager sulks the whole family holiday because he will miss an opportunity to attend a concert.

I like to think that money is not an idol for me, but last month when I checked the bank balance, I found that things were considerably worse than I was expecting. I was in a bad mood about it for a few days as I stewed over in my mind how we could reduce our monthly expenditure. I rationalized this at first as simply being concerned about being a “good steward” of my money. But preparing this sermon on idolatry made me realise that something else was at work too. Could I join Habakkuk in rejoicing even when things are not going my way financially…

Though the fig tree does not bud and there are no grapes on the vines, though the olive crop fails and the fields produce no food, though there are no sheep in the pen and no cattle in the stalls, yet I will rejoice in the LORD, I will be joyful in God my Savior. (Hab 3:17,18 NIV)

Refusal to rejoice in the Lord reveals that something else matters more to us. And that thing, whatever it may be, has become our idol.
