I've been a politician and so I'm sometimes cynical about what politicians won't do. When I hear a politician say something that makes no sense whatsoever, I think there's one of two things there: There's money or the promise of money.

What always strikes me in the story of Cain and Abel is how often the word "brother" is used. Cain killed his "brother." God says it was "the blood of your brother." The killing was done to another human being, a child of God like you, breaking that sacred bond of common humanity.

Ordinary people - churches, too - have a role to force politicians to respond. Governments are not impressed with theories, but governments are impressed with people who change their minds about things.

Ubuntu is not a biblical concept but an ancient African one. Nevertheless it falls back on one simple thing: that humans have been created for togetherness, and what drives us apart is greed, lust for power, and a sense of exclusion, but those are aberrations.

I believe scripture is not just resilient but rebellious against its abuse by people. Scripture says it refuses to be used in that way for long.

Something in the DNA of Christian faith and in the Bible agitates against that kind of misuse.
