living beneath the cross

In a section on confession in the book The Celebration of Discipline, Foster quotes Detriech Bonhoeffer.
How do we learn to receive the confessions of our brothers? By living under the cross!
"Anybody who lives beneath the Cross and who has discerned inthe Cross of Jesus the utter wickedness of all men and of his own heart will find there is no sin that can ever be alien to him. Anybody who has once been horrified by the dreadfulness of his own sin that nailed Jesus to the Cross will no longer be horrified by even the rankest sins of a brother."

Jesus, take me to the place beneath your Cross where this kind of transformation happens!
