Somewhere I heard the quotation, "You can acquire anything in solitude except character." We need the whole community to test us, to refine us, to enable us to develop aspects of character including strength, kindness, and wisdom that we cannot gain without trials. We all need critics and rebukers, malcontents and misfits - even if (especially if?) these cause us pain - so that our feasting is virtuous and honorable.

Indeed. This is the danger for us who live too much in our own heads - we never get tested by the blessing of our community and end up stunting our own sanctification. Blessed is the one whose community is, in the name of our Triune God, building one another up in love (Hebrews 10:24-25).
