An Appearance To James
Within the chronological list of resurrection appearances, a deeply personal and quiet encounter occurred: Jesus appeared to James, His earthly half-brother. Throughout the Gospels, the Lord's brothers were noted for their skepticism, famously urging Him to go to Judea to show Himself to the world, not believing in Him.
This private appearance to James is a turning point in the family of Nazareth. The man who once thought Jesus had lost His mind is completely transformed. James will soon emerge as a prominent pillar and leader of the church in Jerusalem, eventually writing the epistle that bears his name and dying as a martyr for the brother he finally recognized as Lord.
