It’s critical insight is that despite what so many blithely claim, forgiveness is not unconditional! Brauns begins with this simple but profound principle: “God expects believers to forgive others in the way that he forgave them” (p. 44).
For example, Colossians 3:13 speaks of “bearing with one another and, if one has a complaint against another, forgiving each other; as the Lord has forgiven you, so you also must forgive.” (my emphasis). Furthermore, God does not forgive us without our repentance (e.g. Acts 20:21).
Likewise, human forgiveness is not automatic. The key verse here is Luke 17:3: “If your brother sins, rebuke him, and if he repents, forgive him” (NIV, my emphasis). So we do not offer ‘cheap grace’ to people who refuse to acknowledge sin. Of course, we may still act in loving and kind ways towards them, though they be our enemies. Yet we are not obliged to pretend all is okay.
I just ordered my copy today, and hope to share my thoughts after I read it.
