Dietrich Bonhoeffer (1906-1945) was a Lutheran pastor, theologian, anti-Nazi dissident . . .

His writings on Christianity's role in the secular world have become widely influential, and his book The Cost of Discipleship has been described as a modern classic ... Bonhoeffer was also known for his staunch resistance to the Nazi dictatorship, including vocal opposition to Hitler's euthanasia program and genocidal persecution of the Jews. He was arrested in April 1943 by the Gestapo and imprisoned at Tegel prison for one and a half years. Later, he was transferred to Flossenbürg concentration camp . . . and was hanged on 9 April 1945, as the Nazi regime was collapsing.  The following are quotations from the writings of Bonhoeffer on the theme of grace.

• We are torn out of our own existence and set down in the midst of the holy history of God on earth. There God dealt with us, and there he still deals with us, our needs and our sins, in judgment and grace.
• The number one cause of atheism is Christians. Those who proclaim God with their mouths and deny God with their actions is what an unbelieving world finds unbelievable.
• Cheap grace is grace without discipleship, grace without the cross, grace without Jesus Christ, living and incarnate.
• The only person who has the right to say that they is justified by grace alone is the person who has left all to follow Christ. Such a person knows that the call to discipleship is a gift of grace, and that the call is inseparable from the grace.
• Cheap grace is the preaching of forgiveness without requiring repentance, baptism without church discipline, Communion without confession....
• They all stood beneath the cross, enemies and believers, doubters and cowards, revilers and devoted followers. His prayer, in that hour, and his forgiveness, was meant for them all, and for all their sins. The mercy and love of God are at work even in the midst of his enemies.
• It is the same Jesus Christ, who of his grace calls us to follow him, and whose grace saves the murderer who mocks him on the cross in his last hour.
• Those who try to use cheap grace as a dispensation from following Christ are simply deceiving themselves.
• Self-justification and judging others go together, as justification by grace and serving others go together
• It is grace, nothing but grace, that we are allowed to live in community with Christian brethren.
• The world upon whom grace is thrust as a bargain will grow tired of it, and it will not only trample upon the Holy, but also will tear apart those who force it on them.
• God honors some with great suffering and grants them the grace of martyrdom, while other are not tempted beyond their strength. But in every case it is one cross.
