From my daily devotional:
There is no end to the spending, getting, having. We are insatiable consumers, dead set on competing, upgrading, showing off ("If you've got it, flaunt it"). We simply cannot bear to miss something others deem necessary. So the world ruins the peace and simplicity God would give us. Contentment with what He has chosen for us dissolves, along with godliness, while, instead of giving thanks, we lust and wail, teaching our children to lust and wail too.
