Among his most influential books are Moral Man and Immoral Society and The Nature and Destiny of Man, the second of which Modern Library ranked one of the top 20 nonfiction books of the twentieth century. Starting as a minister with working-class and labor class sympathies in the 1920s oriented to theological pacifism, he shifted to neo-orthodox realist theology in the 1930s and developed the theo-philosophical perspective known as Christian realism. He attacked utopianism as ineffectual for dealing with reality, writing in The Children of Light and the Children of Darkness :.. (wikipedia)

God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference.
Goodness, armed with power, is corrupted; and pure love without power is destroyed.
The final wisdom of life requires not the annulment of incongruity but the achievement of serenity within and above it.
God, give us grace to accept with serenity the things that cannot be changed, courage to change the things which should be changed and the wisdom to distinguish the one from the other.
