I have quite a few in place - I want to be a Minister for the long haul; don't burn out; protect the family; observe your day off.
I have read a really scary book about clergy burn out called 'The Cracked Pot.'
My boundaries are generally eminently sensible.
But what if they might be a bit too sensible?
For example, I have always protected some time to write my sermon each week.
This week it just didn't work.
A reunion; a funeral; visitors; Regatta; end of term; a late night train trip...I could feel stress rising and control of the diary slipping hopelessly.
It was Saturday evening when I realised the sermon wasn't going to get written.
And then there's wearing the dog collar: I do when I'm being 'Minister'; when I'm shopping, picking up kids, or travelling socially I generally don't.
But for various reasons I spent all day Saturday in it.
Across London on the Tube; through a major city; eating at Nando's. The occasion called for it and it seemed right, but again it blurred my boundaries.
After that major day on Saturday I was very late to bed and up early Sunday for two Holy Communions. Not sensible.
So I had no sermon at 9.30am Parish Communion save what was in my head. I hadn't really 'prayed about' either service.
My careful plans to allocate time to important things had been interrupted all week.
So I blundered in. I preached with no notes. It was the least prepared I'd ever been for a Sunday morning.
And yet it was a really great Sunday!
It was joyful. It was enjoyable.
It felt spontaneous and hopeful.
So I'm thinking maybe God is less boundaried than I am.
The gospel reading today was about Jesus being hassled and boundaries being breached; the touch of a haemorrhaging woman significantly interrupted his journey to a dying girl. Ritual uncleanness and death.
Jesus didn't hesitate in crossing both boundaries with willing openness.
A little less planning and a little more trusting then.
