Fifty years ago today (28th August, 1963) Martin Luther King, a Christian minister committed to non-discrimination and non-violence, led a march of 250,000 people, three-quarters of whom were African-American, to Washington DC.  There he shared his dream:-

I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at a table of brotherhood.

I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice and sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice.

I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.

I have a dream that one day, down in Alabama, with its vicious racists…little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers…

With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day…

John Stott has commented:-

We are still waiting for the fulfilment of his dream.  Yet it is a Christian deam.  God has given us in Scripture a vision of the redeemed as “a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne” (Revelation 7:9).  That dream, we know, will come true.  Meanwhile, inspired by it, we should seek at least an approximation to it on earthm namely a society characterised by justice (no discimination) and harmony (no conflict) for all ethnic groups.  We are looking for a fully integrated society which continues to celebrate diversity.
