“The truth is that so long as we hold both sides of the proposition together they contain nothing inconsistent with right belief, but as soon as one is divorced from the other, it is bound to prove a stumbling block. "Only those who believe obey" is what we say to that part of a believer's soul which obeys, and "only those who obey believe" is what we say to that part of the soul of the obedient which believes. If the first half of the proposition stands alone, the believer is exposed to the danger of cheap grace, which is another word for damnation. If the second half stands alone, the believer is exposed to the danger of salvation through works, which is also another word for damnation.”
Dietrich Bonhoeffer was a German Lutheran pastor and theologian. He was also a participant in the German Resistance movement against Nazism, a founding member of the Confessing Church. His involvement in plans by members of the Abwehr (the German Military Intelligence Office) to assassinate Adolf Hitler resulted in his arrest in April 1943 and his subsequent execution by hanging in April 1945, shortly before the war's end.
Overshadowed by his life and death, his theology and his view of Christianity's role in the secular world has nevertheless remained very influential.
He seems to have undergone something of a personal conversion from a theologian primarily attracted to the intellectual side of Christianity to a dedicated man of faith, resolved to carry out the teaching of Christ as he found it revealed in the Gospels.
