Beyond expectations
Format: Hardcover
Hands down, this is the best commentary I have read on 1&2 Thessalonians. Weima takes the reader deep into the First Century world covering everything that would have influenced the recipients as well as the sender of these letters. The research on its own is phenomenal.
