Dietrich Bonhoeffer said this quote
“ A Christian fellowship lives and exists by the intercession of its members for one another, or it collapses. I can no longer condemn or hate a brother for whom I pray, no matter how much trouble he causes me. His face, that hitherto may have been strange and intolerable to me, is transformed in intercession into the countenance of a brother for whom Christ died, the face of a forgiven sinner. ”
