In the Flesh: Is healing a thing?

Episode 22: Many forms of Christianity (along with other religions too) hold to a belief that God can heal physical bodies in answer to prayer. In some streams, there are particularly potent versions that claim healing as a promised answer to prayers of faith and conviction. But there's a lot of dishonesty in this conversation, and the reality of people's experience seldom matches the rhetoric. So what do we do with this? Is healing a thing, or is it just wishful thinking? Is talk of God "intervening" in our lives a helpful way to conceive of God, and how does this impact on the way we think about prayer and healing?
