Why are people sceptical about spiritual and miraculous healing? Mostly because they simply don't believe it. The prevailing secular atheist worldview has no slot available for this kind of thing - it simply doesn't happen (although a more thoughtful and informed atheist might allow for some kind of psychosomatic factor in healing). But even among those who are less rigidly rationalist, there is huge cynicism about miraculous healing, because there has been so much deceit and abuse practised on people in the name of healing, and especially in the name of Christian healing.
I admit my sympathies are often with them. I've seen too many people hurt by false expectations of healing, too many Christians credulously swept along by the latest wave of "miracles" perpetrated by someone trying to make a fast buck, and quite frankly, too much lying by so-called Christian leaders, to be anything other than very cautious when presented with amazing claims of divine intervention. But, on the other hand, I've seen enough to know that God is not bound by our scepticism and amazing things do sometimes happen.
Let's look at the arguments people are using to say that this is a hoax. Argument number one is "I don't believe this". This is most people's idea of a clincher, but really is completely useless in logical terms, as C. S. Lewis would tell you (what do they teach them in these schools nowadays?). You may for example, be utterly convinced that black is white, but that doesn't make you right. You may never have seen a Giraffe, but that in itself doesn't mean Giraffes don't exist. And even if all your friends share your wrong views, they are still just as wrong.
In fact the only way of evaluating the authenticity of something like this is by looking at the evidence. If the evidence doesn't stack up, then this is a cruel hoax. If it does, then cynicism has to take a hike.
The first knock of doubt for the cynics comes from the identity of the person concerned. As far as I can tell, Delia Knox has been known as a wheelchair user for many years. She has had a high-profile role as a singer and charismatic pastor, sharing a ministry with her husband, Levy Knox. She is not an anonymous fake who has been produced like a rabbit out of a hat to be conveniently "healed". She has a past which ought to be verifiable. Read her bio here and take a look at this video on her website. Also this one below, which to me is more impressive and moving than the "show" one which the mail picked up on:
You can see that at this point she was still quite shaky on her feet, something which makes this more convincing rather than less. The other thing I find persuasive is the way in which this has been publicised. Fake healings are intended to boost the reputation (and usually the income) of the person responsible, the smooth-talking "evangelist" with the global ministry, send your credit card details to this number. That isn't the case here. It's striking that the evangelist who prays for her is hardly name-checked at all in the "miracle" video, and he isn't (at the moment) out there trying his damndest to cash in on it, as we would expect from a fake. Even the Knox's own elaborate website still only mentions the incident as an add-on, indicating that they are still adapting to their changed circumstances. You might also like to look at their Facebook page, which describes this as a "progressive miracle", a careful description that doesn't smack of sensationalism.
It's always possible that what appears genuine at first might turn out to be a deception, bruising our faith once again. But on the basis of what I've seen, I'm persuaded. And why not? As the Nativity plays out on prime-time TV in the UK, Christians are reminded that they believe that God sent his Son to walk among us, "a bridge between heaven and earth", as the scriptwriter put it. If you believe that, then what greater miracle could there be for you to put your faith in? Is there anything more incredible and wonderful than the eternal Word incarnate, Mary's baby born to change the world? Anything else is just a lesser miracle than reminds us of the great one.
And if you don't believe it, then I can understand why you look at Delia Knox and see snake oil, smoke and mirrors, and a nasty mirage. But if the evidence didn't justify that view, would that make you think again about the other miracle, the child in the manger?
