He’s started a series on the book of Jonah. So far he’s posted an introductory podcast on Jonah 1:1 as well as one on the importance of genre — which actually deals more with Amos 4:4-5 (rather brilliantly, I might add).
I strongly encourage you to check it out — it’s really pretty cool. The podcasts are informative and witty — and Tim’s New Zealand accent alone is worth the five minutes!
