Dietrich Bonhoeffer, from A Testament to Freedom,
Do what is right not only to respectable citizens, but especially to the disrespectable ones as well; be at peace not only with those who are peaceable, but especially with those who do not wish to let us live in peace. Even the heathen can live at peace with those who are peaceable to them. But Jesus [Messiah] died not for those who are respectable and peaceable, but for sinners and enemies, for the disrespectful, for the haters and killers.
Our hearts make sure that we only keep the company of friends, of the righteous and the respectable. But Jesus was to be found right in the midst of his enemies. That is precisely where he wanted to be. We should be there too. It is that which distinguishes us from all other teachings and religions. In them, the pious want to be with one another. But [Messiah] wants us to be in the midst of our enemies, as he was; it was in the midst of his enemies that he dies the death of God's love and prayed: Father, forgive them for they know not what they do. [Messiah] wants to win his victory among his enemies. Therefore, do not withdraw, do not seclude yourselves; rather seek to do good unto all.
Make peace, as far as it depends on you, with all.
