Dietrich Bonhoeffer said this quote

Jesus Christ lived in the midst of his enemies. At the end all his disciples deserted him. On the Cross he was utterly alone, surrounded by evildoers and mockers. For this cause he had come, to bring peace to the enemies of God. So the Christian, too, belongs not in the seclusion of a cloistered life but in the thick of foes. There is his commission, his work. 'The kingdom is to be in the midst of your enemies. And he who will not suffer this does not want to be of the Kingdom of Christ; he wants to be among friends, to sit among roses and lilies, not with the bad people but the devout people. O you blasphemers and betrayers of Christ! If Christ had done what you are doing who would ever have been spared' (Luther).

~ Dietrich Bonhoeffer

Action springs not from thought, but from a readiness for responsibility.

~ Dietrich Bonhoeffer

As you gave the ring to one another and have now received it a 2nd time from the hand of the pastor, so love comes from you, but marriage from above, from God. As high as God is above man, so high are the sanctity, the rights, and the promise of love. It is not your love tht sustains the marriage, but from now on, the marriage that sustains your love.

~ Dietrich Bonhoeffer

Many people seek fellowship because they are afraid to be alone...let him who cannot be alone beware of community. He will do harm to himself and to the community. Alone you stood before God when he called you; alone you had to answer that call; alone you had to struggle and pray; and alone you will die and give an account to God. You cannot escape yourself, for God has singled you out.

~ Dietrich Bonhoeffer
