On the morning of April 9, 1945, German pastor Dietrich Bonhoeffer was executed at Flossenburg concentration camp. The camp doctor, H. Fischer-Hullstrung, later remembered: [Just before the execution] I saw Pastor Bonhoeffer kneeling on the floor, praying fervently to God…so certain that God heard his prayer…I have hardly ever seen a man die so entirely submissive to the will of God.

Others testified that, up to his last day, the 39 year-old Bonhoeffer remained cheerful. He knew what he had to do, was reconciled to God’s will, and was able to climb the steps to the gallows “brave and composed.”

Who was this man who died so bravely—who Hitler himself, from his bunker beneath Berlin just three weeks before his suicide, ordered to be “destroyed?” He is the subject of best-selling author Eric Metaxas’ new biography: Bonhoeffer: Pastor, Martyr, Prophet, Spy.
