What do you know about Gordon Brown, Britain's new Prime Minister? While I was in Cambridge last month, I read about him.

My American friend, Jim Wallis, writes "I was speaking in Britain and got a call from the Office of the Chancellor of the Exchequer (his former position) saying that Brown wanted to get together that evening, if I was available. So I went over to his office at the Treasury, and he told me that he had read my books and had many questions for me. So we put our feet up and began talking, and have been doing so now for a number of years."

I've done several interviews recently with British newspapers and television networks about what kind of man Gordon Brown is. One asked me the word I would use to best describe him, and I said "passion." That's in sharp contrast to some of the British press, who refer to the new Prime Minister as "dour."

Visitors are universally and amazingly impressed with his deep understanding of the issues of globalization and his personal commitment to tackling the moral challenge of inequality. Gordon Brown has more passion (and knowledge) about the issues of global poverty and social justice than any other Western leader today. And, I believe his leadership could make a great difference. "He is somebody you should know and follow closely," says Jim Wallis.

Gordon Brown is the son of a Church of Scotland pastor and grew up in a manse where the biblical vision of justice seems to have found its place in his heart. Quotes from Isaiah and Jeremiah pepper his speeches about the kind of global economy we must be working for, and as I said in God's Politics, Brown's words often remind me of the prophet Micah, who knew that true security requires that "all sit under their own vines and under their own fig trees, and no one shall make them afraid."

Let me share a few of his words from his speech this week on his transition to the new post of Labor Party Leader and Prime Minister.

First on his values and moral compass: "All I believe and all I try to do comes from the values that I grew up with: duty, honesty, hard work, family, and respect for others. And this is what my parents taught me and will never leave me: that each and every one of us has a talent, each and every one of us should have the chance to develop their talent, and that each of us should use whatever talents we have to enable people least able to help themselves.

And so I say honestly: I am a conviction politician. My conviction that everyone deserves a fair chance in life. My conviction that each of us has a responsibility to each other. And my conviction that when the strong help the weak, it makes us all stronger. Call it "the driving power of social conscience," call it "the better angels of our nature," call it "our moral sense," call it a belief in "civic duty."

I joined this party as a teenager because I believed in these values. They guide my work, they are my moral compass. This is who I am. And because these are the values of our party, too, the party I lead must have more than a set of policies - we must have a soul.

On children in poverty: "... let me say also that in the fourth richest country in the world it is simply wrong - wrong that any child should grow up in poverty. To address this poverty of income and to address also the poverty of aspirations by better parenting, better schools, and more one-to-one support, I want to bring together all the forces of compassion - charities, voluntary sector, local councils, so that at the heart of building a better Britain is the cause of ending child poverty."

On foreign policy: "Our foreign policy in years ahead will reflect the truth that to isolate and defeat terrorist extremism now involves more than military force - it is also a struggle of ideas and ideals that in the coming years will be waged and won for hearts and minds here at home and round the world. And an essential contribution to this will be what becomes daily more urgent - a Middle East settlement upholding a two state solution, that protects the security of Israel and the legitimate enduring desire for a Palestinian state.

Because we all want to address the roots of injustice, I can tell you today that we will strengthen and enhance the work of the department of international development and align aid, debt relief and trade policies to wage an unremitting battle against the poverty, illiteracy, disease and environmental degradation that it has fallen to our generation to eradicate."

Gordon Brown is a new kind of political leader, one who seeks to practice moral politics. He has already worked very closely with the community of faith and seeks a vital partnership. He knows that even politicians like him need to be challenged and held accountable by social movements with spiritual foundations. He once told Jim Wallis that without the church-based movement to cancel Third World debt, the Labor government would have never done so. He encourages us to keep building such movements because the world of politics needs them.

So pay attention to what Gordon Brown does now and please pray for him. I believe he could become the kind of international leader who really helps to change things. I watched his remarks on TV, just before he and his wife walked through the door of 10 Downing Street to spend his first night as Prime Minister of the United Kingdom. I'm glad he is there
