One of the 20th century heroes of our faith is Dietrich Bonhoeffer. He was a German pastor who led several efforts to condemn, resist, and overthrow Adolf Hitler as he rose to leadership. He also helped rescue Jews from Nazi Germany. However, Bonhoeffer was found out as a member of the resistance and imprisoned.
During his imprisonment, he ministered to others prisoners and wrote letters encouraging his family and friends. He wrote, “God lets himself be pushed out of the world on to the cross. He is weak and powerless in the world, and that is precisely the way, the only way, in which he is with us and helps us. [The Bible] … makes quite clear that Christ helps us, not by virtue of his omnipotence, but by virtue of his weakness and suffering… The Bible directs man to God’s powerlessness and suffering; only the suffering God can help.”
Bonhoeffer’s writings remind us that our Savior is able to fully sympathize with us in our sufferings while still being sovereign over all
