I've just started Mark Buchanan's book, The Rest of God and I know it's going to be a delight.
On his opening page he referenced 2 Peter 1:12-15 and then said this -
"These verses define what I'm about, as both a writer and a speaker; the ministry of reminding - of restating truth we already know. I do this always, and I will do it as long as I'm around, so that even after I've departed, the memory of truth will live on. I hope what I write is fresh, but there is nothing original. It's all just a reminder."
What Mark writes is always fresh and the way he writes it makes you want to slow down and savour.
