Consumerism has given us many globally recognisable shapes. Creative types might think instantly of iconic design profiles: the figurine coke bottle, the Nike swish, the sleek Apple Mac. The cynical among us might suggest more sinister outlines: the increasing Western waistline, the reducing Arctic ice.

But nothing the consumer mould produces is as significant as this: the way it shapes our souls. The problem with consumer culture, to put it bluntly, is not so much the products it makes – these can be ingenious, useful and, increasingly, more sustainably produced. The problem is not so much the mess it makes – this is a massive global challenge, but still only a symptom of a deeper malaise. The problem with consumer culture is the people it makes.

Let’s make this personal. The problem is me. ‘Hi, my name’s Mark and I’m a consumer.’

The truth is that I am hugely shaped by my addiction to stuff. I am formed by my fear of a dull, reduced life. I am defined by the ever-present danger of lagging too far behind the consumer pack. Funnily enough, I don’t feel addicted. But, at the same time, I really don’t want to be the only person who hasn’t seen the latest blockbuster / hasn’t been skiing / isn’t culturally up-to-date (delete as appropriate). All this is deeply formational, and the shape it gives me is a rushed, dissatisfied and self-focussed life.

God is, of course, in the formation business too. He has a particular shape in mind for us – ‘to be conformed to the image of his Son’ (Romans 8:29). It’s an image of suffering and glory, as Paul makes clear. It’s an image of generosity and blessing (at times ‘poor, yet making many rich’ – 2 Corinthians 6:10 – easy now, Paul!). Eugene Peterson calls it ‘the soaring and swooping life of grace’.

Or we could say ‘less stuff, more life’.
