Cheap grace is the deadly enemy of our church. Cheap grace means grace sold on the market like cheapjack’s wares. Cheap grace is the preaching of forgiveness without requiring repentance, without church discipline, communion without confession, absolution without personal confession.
A man who confesses his sins in the presence of a brother knows that he is no longer alone with himself; he experiences the presence of God in the reality of the other person. As long as I am by myself in the confession of my sins, everything remains in the clear, but in the presence of a brother, the sin has to be brought into the light.
