What is the church in a nutshell?

The church is not a theological classroom. It is a conversion, confession, repentance, reconciliation, forgiveness, and sanctification center, where flawed people place their trust in Christ, gather to know and love him better, and learn to love others as he has designed. The church is messy and inefficient, but it is God's wonderful mess -- the place where he radically transforms hearts and lives.
