When I am in niminypiminy, firstly I draw strength from myself, because ultimately, I have only myself to rely on. Secondly, I draw on those around me. But I certainly don't rely on any celestial being's goodwill to make it better.
I used to be an evangelical Christian. I went to church, I sang, I prayed, I spoke in tongues. But I still felt empty. I sought god with all my heart, my soul and my mind. I wanted, with every cell of my being, to know him, to serve him, to feel his hand in my life. I cried out to him to fill me with that comfort, that warmth, that sense of purpose that the other members of my church seemed to feel. They cried with happiness at the joy god apparently brought them.
All I felt was the uncaring coldness of a universe in which I mattered not one jot.
Then I gave up on god, and the second I took control of my own life, that I accepted there was nothing but me, that I had complete control over my own destiny... that was the moment when I knew true peace and joy.
In the example you give, where the partner has dementia, well, even as a Christian, unless you have dementia too, there is still no witty intelligent person to talk to. In my experience, god doesn't have witty intelligent conversations with people. It's just you talking things through with yourself in your head. How is a belief in god remotely helpful apart from letting you believe there's a purpose in the horrible thing that's happening to you?
Christians may draw strength from there being some imagined purpose. I draw strength from the simple knowledge that life has ups and downs. So while right now may be a down, statistically speaking, an up is bound to follow sooner rather than later. And since I take responsibility for my own destiny, I will work at improving my situation in any way I can rather than wailing to god to fix it for me.
Things just are. Why does there need to be more?
Tim Minchin says it very well in his :
Isn't THIS enough?
Just.. this.. world?
Just this.. beautiful, complex
Wonderfully unfathomable.. natural.. world?
How does it so fail to hold our attention
That we have to diminish it with the invention
Of cheap, man-made myths and monsters?
If you're so into your Shakespeare
Lend me your ear:
"To gild refined gold, to paint the lily,
To throw perfume on the violet, is just fucking silly"
Or something like that.
Or what about Satchmo?!
"I see trees of green,
Red roses too",
And fine, if you wish to
Glorify Krishna and Vishnu
In a post-colonial, condescending
Bottled-up and labeled kind of way
Then whatever, that's ok.
But here's what gives me a hard-on:
I am a tiny, insignificant, ignorant bit of carbon.
I have one life, and it is short
And unimportant
But thanks to recent scientific advances
I get to live twice as long as my great great great uncle-es and aunt-es.
Twice as long to live this life of mine
Twice as long to love this wife of mine
Twice as many years of friends and wine
Of sharing curries and getting shitty
At good-looking hippies
With fairies on their spines
And butterflies on their titties.
