Everyone has a frontline, a place where the nature of the Kingdom of God and our citizenship of that Kingdom is challenged and critiqued by other powers or values. Usually that place is not the Church but our neighbourhood, place of work, even our home or our leisure activity. Frontline is by default a place of witness, ministry and challenge. How do we identify what our frontline is? What has the gospel to say about how we work out our earthly citizenship? How do the places where we go away from our Christian fellowship challenge our faith or call out good things from us?
