Now that I have your attention on the Blumhardts, here is the very first English translation of the standard German biography of the elder Blumhardt, Johann Christoph. This is the first in what will become a 10-book series edited by my colleague Christian Collins Winn.
The price-tag is aimed more at libraries than individuals, but it’s well worth looking up.
I hope to give it at least a quick read over the coming months and report back. Meanwhile, you might want to click the link above and then either pick it up or look for it through your local library system.
