The Training of the Twelve By A. B. Bruce (PDF)
This book is a classic study of Jesus’ teaching and training of his disciples (first published in 1871). When I first read it, I was fascinated by the light it shed on my reading of the Gospels. It is a very valuable study for any Christian who serves in any form of leadership capacity or anyone seeking to be a disciple of Jesus Christ.
The book’s 31 chapters give an absorbing commentary on selected passages of the four Gospels, following in chronological order Jesus ministry and teaching among his disciples. The writing style will take a bit of getting used to for the average modern reader, but it’s well worth the effort.
