The spirit of obedience is necessary not only in monks, but everyone else, too. Even the Lord was obedient. The proud and those who are a law unto themselves prevent the indwelling of grace and therefore never know peace of soul; whereas the grace of the Holy Spirit enters with ease into the soul of the obedient, bringing joy and quiet.
