Being a Guest Preacher

We're off to visit Liz's Mum and Dad this weekend. Nothing particularly unusual in that, but I'm a bit more nervous than usual. Wallace has invited me to preach for one of the congregations at the church he leads. And it's not on any old Sunday, but Pentecost, the church's birthday. It also happens to be Wallace's birthday. No pressure then :-) Please pray for us, especially if Liz succeeds in persuading me that we ought to go shopping for a new mattress this afternoon!
