The only sure rule is to remember that the Bible is indeed God's gift to the church, to equip that church for its work in the world, and that serious study of it can and should become one of the places where, and the means by which, heaven and earth interlock and God's future purposes arrive in the present.

When Jesus's followers asked him to teach them to pray, he didn't tell them to divide into focus groups and look deep within their own hearts.

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.

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 convinced that when we bring our griefs and sorrows within the story of God's own grief and sorrow, and allow them to be held there, God is able to bring healing to us and new possibilities to our lives. That is, of course, what Good Friday and Easter are all about.

What you do in the present—by painting, preaching, singing, sewing, praying, teaching, building hospitals, digging wells, campaigning for justice, writing poems, caring for the needy, loving your neighbor as yourself—will last into God’s future. These activities are not simply ways of making the present life a little less beastly, a little more bearable, until the day when we leave it behind altogether. They are part of what we may call building for God’s kingdom.

But the voice goes on, calling us, beckoning us, luring us to think that there might be such a thing as justice, as the world being put to rights, even though we find it so elusive. We're like moths trying to fly to the moon. We all know there's something called justice, but we can't quite get to it.
