Guy Davies interviews Derek Thomas here
They discuss preaching, biblical and systematic theology, pastoral ministry, and Wales.
Turns out that Del Boy's favourite movie is How Green Was My Valley. There is lovely. I read the book when I was an A-level student. Derek, tolle lege.
There is a word in the interview that needs some explaining to non-Welsh readers. Guy asks Derek about whether he still gets hiraeth. It means longing and homesickness. Welsh people suffer from it terribly. They only have to cross the Severn bridge into England and it sets in.
If you would like to see a bit of How Green Was My Valley, I've posted a clip from the movie here.
