Money can become a spiritual addiction, and like all addictions it hides its true proportions from its victims. We take more and greater risks to get an ever diminishing satisfaction from the thing we crave, until a breakdown occurs. When we begin to recover, we ask, ‘What were we thinking? How could we have been so blind?’ We wake up like people with a hangover who can hardly remember the night before. But why? Why did we act so irrationally? Why did we completely lose sight of what is right? The Bible’s answer is that the human heart is an ‘idol factory.’ When most people think of ‘idols’ they have in mind literal statues – or the next pop star anointed by Simon Cowell. Yet while traditional idol worship still occurs in many places of the world, internal idol worship, within the heart, is universal. In Ezekiel 14: 3, God says about elders of Israel, ‘These men have set up their idols in their hearts.’ Like us, the elders must have responded to this charge, ‘Idols? What idols? I don’t see any idols.’ God was saying that the human heart takes good things like a successful career, love, material possessions, even family, and turns them into ultimate things. Our hearts deify them as the center of our lives, because, we think, they can give us significance and security, safety and fulfillment, if we attain them.
