Status Updates From Deliverance to the Captives

“If I were asked to put into one sentence the basic principle that underlies all of Barth’s theology I think I would say that it is directed, all the way through, to but one end—to leave completely undistorted and uncompromised the great, wonderful and mysterious fact that God has spoken to us in his Son, Jesus Christ out Lord.” — John Marsh from the preface

The sermon "Number Our Days" has Barth's explanation of the cross, and the sermon "God's Good Creation" gives some hints towards his idea of creation.
