Jesus emerges as the morally transformative teacher in the book of James. The once unbelieving half-brother of Jesus (see John 7:5), James came to see that Jesus was the supreme teacher, the only one who can show us how to live a transformed life.
He never entered a classroom as we know a classroom. He never had a degree as we understand an educational degree, yet all the world was his classroom. No degreed teacher did anything greater than what Jesus Christ did. He was truly and absolutely the Master Teacher and the greatest teacher of all time. – Ray Pritchard
