There can be no maturity in the spiritual life, no obedience in following Jesus, no wholeness in the Christian life apart from an immersion and embrace of community.  I am not myself by myself.  Community, not the highly vaunted individualism of our culture, is the setting in which Christ matures us.
 -- Eugene Peterson
The line that jumps out at me here is 'I am not myself by myself'.  ...some would argue mightily with this.  But, I think this is worth serious consideration.
