From a video by Christian Aid:

Christian leaders, including Jim Wallis (Sojourners), John Bell (Iona Community) and the Bishop of Durham (England), reflect on the biblical call for justice. This film was produced by the video team at Christian Aid, the international development agency of the churches of the UK and Ireland. Christian Aid works wherever the need is greatest – irrespective of religion or race. For more info, please visit http://www.christianaid.org.uk/
