Last year I preached twice on a Sunday every second week during summer, otherwise I generally preached once on a Sunday. With the change in societies I am now able to be at both societies much more often and so am starting to preach twice most weeks. It is good and I think that I can already see the impact, but I'd forgotten how tiring it is!
I think that I will get back into the habit of it, though as I used to regularly preach two to three times a week, but - I was younger then . . .
I can't lose the sense of privilege I have when I watch the congregations that God has trusted me with at worship.
