Confession: how to get free
“The more isolated a person is, the more destructive will be the power of sin over him, and the more deeply he becomes involved in it, the more disastrous is his isolation. Sin wants to remain unknown. It shuns the light. . . . In confession the light of the gospel breaks into the darkness and seclusion of the heart. The sin must be brought into the light. The unexpressed must be openly spoken and acknowledged. All that is secret and hidden is made manifest. It is a hard struggle until the sin is openly admitted. But God breaks gates of brass and bars of iron.”
Dietrich Bonhoeffer, Life Together (New York, 1954), pages 112-113.
