At the heart of Christian ethic is humility; at the heart of its parodies, pride. Different roads with different destinations, and the destinations color the character of those who travel by them.

I am also very excited by the way in which we can see Paul wrestling not only with his Jewish world and its scriptures but also, by clear implication, with philosophical and political issues that were 'out there' at the time. The thing is that for Paul this is all part of the same larger, whole vision of God and God's purposes. Watching how everything comes together is an intellectual treat of the first order - as well as a spiritual and practical challenge to me personally and to the church.

I really don't care too much what the different later Christian traditions say. My aim is to be faithful to Scripture.

Again and again the Sermon on the Mount calls and challenges us to a life of radical discipleship. Note: when Jesus says 'Blessed are the . . . . merciful, peacmakers', and so on, he doesn't just mean that they themselves are blessed. He means that the blessing of God's kingdom works precisely through those people into the wider world. That is how God's kingdom comes. That's one thing to hear afresh.

When you're writing theology, you have to say everything all the time, otherwise people think you've deliberately missed something out.

From where many of us in the U.K. sit, American politics is hopelessly polarized. All kinds of issues get bundled up into two great heaps. The rest of the world, today and across the centuries, simply doesn't see things in this horribly oversimplified way.

I believe we face the question: if not now, then when? And if we are grasped by this vision, we may also hear the question: If not us, then who? And if the gospel of Jesus is not the key to this task, then what is?
