I think I do. I'm Catholic and I do believe in God and the Devil, so I would like to believe that they exist too. I find the idea rather comforting.
Now let me tell you DH's weird story and see what you think...:o
About 17 years ago, DH contracted NHL (non-hodgkins lymphoma), a particuarly nasty and pervasive variety that had spread to all his glands and was destroying his blood cells.
He was given 6 years to live as a top estimate - he could have chemo, it would go away for approx 3 years but would definitely come back, he could then have more chemo and perhaps get another 3 years, but then it would come back and by then the chemo would have destroyed his liver and kidneys so he couldn't have any more treatment.
As you can imagine, we were pretty devastated. We'd been married 3 years and trying to start a family (I was 28 at the time) and it felt like the end of everything. However, he embarked on the initial chemo to shrink the enormous tumour in his spleen and, while he was in recovery from that, his work had arranged for him to have an internet connection put in at home (it was all dial up back then) so that he could, if he felt up for it, work from home.
He looked up his condition and found that an American university had invented a radical new treatment for NHL, and were testing it in 3 sites worldwide - the university itself, Berlin, and St Barts in London. DH asked his doctor if he could be put forward for the program, he applied and was accepted.
The treatment went ahead, he was basically radioactive for 3 months, when he came home I had to move out (slept on a friend's sofa) and could only see him for 20 mins a day to begin with, he wasn't allowed near the elderly or the very young or ill, it was all a bit traumatic.
Before he went in for the treatment, despite being an aetheist all his life, he asked me to buy him a bible. I was actually quite pissed off with him at the time, despite being Catholic myself I kind of felt that he should stick to his principles and not 'cave' to Christianity purely because he was scared of dying. Which probably makes me a horrible Christian, I should have been pleased, but I wasn't... However, I got him the bible. In the meantime me, my mum, her church, my church and lots of other people were praying for him.
However.... and this is the weird bit....
Again, just before the treatment, he was home and I wasn't, there was a knock at the door. Two men were stood there, men he's never seen before or afterwards, dressed quite casually, nothing odd about them but (this is DH's account of what happened) they just emanated this sense of peace and reassurance. They said to him that they'd heard he'd been through some very hard times, and that there were hard times to come, but that they were here to tell him that everything was going to be all right. That he would be okay. And that he shouldn't worry about a thing, the power of prayer was a positive force for him.
He said (and he is not a superstitious or 'woo' kind of person in the slightest) that he instantly felt 'uplifted', warm and totally at peace. They left and he carried on feeling that way, right up until he was told he was in full remission, that all the cancer cells had been destroyed. Then he told me about it, because he'd felt embarrassed to do so before then.
(I, being a cynical moo, asked him if they were JW, but he said not (and to be fair they always come suited and booted) and they weren't selling anything either.)
Soooo... angels? Random blokes spreading goodwill? Hallucination? I don't know. But it makes me feel happy to think that someone might be watching over us.
