Our books came out just days apart back in March. We drew from much of the same research. And we came to virtually the same conclusion: Now is the time to tackle global poverty and suffering—and it’s up to us to do it.

The main difference? Peter Singer approached his argument in The Life You Can Save from an ethicist (and atheist) point of view; I approached mine from a Christian perspective.

This afternoon, Peter Singer and I are appearing together at Harvard University to talk about our shared call to action. It’s compelling that there’s so much common ground between us, despite our divergent backgrounds. I’m looking forward to our exchange.

Some people might say that I shouldn’t engage with an avowed atheist who has liberal views. But global poverty is so staggering, the issues so urgent, that making a difference will take all of us. We don’t have to agree with each other’s philosophies to collaborate. I believe that people of good faith can work with those of good will to accomplish great things.

But what do you think? Can Christians work alongside the Peter Singers of the world? If so, how? What has been your experience of working with people of diverse viewpoints to fight poverty, locally or globally?

Next week I’ll write about the Harvard event. I’ll try to make a podcast available if you’d like to listen for yourself.
