In many ways, when you're a Nobel peace laureate, you have an obligation to humankind, to society.

We have a planet that is at risk, where resources don't have a permanent life. We are going to have to make the decision: are we going to survive or are we waiting for our extinction? One day we will wake up and find people are fighting not for oil but water.

There is no peace in Southern Africa. There is no peace because there is no justice. There can be no real peace and security until there be first justice enjoyed by all the inhabitants of that beautiful land. The Bible knows nothing about peace without justice, for that would be crying "peace, peace, where there is no peace". God's Shalom, peace, involves inevitably righteousness, justice, wholeness, fullness of life, participation in decision-making, goodness, laughter, joy, compassion, sharing and reconciliation.

I mean in the South African case, many of those who were part of death squads would have been respectable members of their white community, people who went to church on Sunday, every Sunday.

The God who existed before any religion counts on you to make the oneness of the human family known and celebrated.
