L'Abri Retreat: Bonhoeffer on Formation

My students and I recently enjoyed a weekend retreat at L'Abri Fellowship in Yang Yang.  I was asked by L'Abri's director Inkyung Sung to give a talk on Bonhoeffer.
We explored Bonhoeffer's ideas on God's work of forming the follower of Jesus into the image of Christ.  We examined the goal, path and pattern of the journey through which the follower becomes the imitator of Christ.
