He was differentiating between complaining and lamenting and noting that complaining is ultimately self-centered whereas lamenting is God-centered.  We complain when things aren’t the way we want them, and lament when things aren’t the way God wants them.  So, whereas true lament ought to drive us into God-centered community, when we complain we often merely seek out others who will either affirm our self-centeredness because they “love” us or because they are similarly self-centered and happen to agree with what we are complaining about.

So, I guess all I am saying here is that self-centeredness is a form of idolatry and it’s all the more subtle (and perhaps all the more insidious) when we can find others who join us in the elevation of self over God.
