Preaching during his installation service, the Rt Rev Stephen Cottrell invited people to "begin again" and bear the Good News during Advent.
"If we live prayerful, faithful lives, if we shine with the light of the risen Christ, then or world will be changed," he said.
"For God's big society is made up of a thousand little deeds of sacrifice and kindness."
Bishop Cottrell is a keen advocate of rest over the Christmas period. He previously penned the book 'Do Nothing: Christmas is Coming' and has just co-authored a new book for this Advent with a similar message.
'Ready Steady Slow' invites people to set aside five minutes of their day and change the world by following daily 'tread gently' challenges.
These include making your own compost, holding a paperless party, driving slower, and indulging in a longer coffee break.
