29AD: the Parable of the Unforgiving Servant
In response to Peter's question about forgiveness, Jesus tells the parable of the unforgiving servant. In the parable, the Master forgave his servant the equivalent of $3.5 billion, yet he didn't forgive his servant the equivalent of $5 thousand. The message is that the equivalent of what we hang onto when we don't forgive or surrender is nothing compared to what Jesus paid on the cross.
Matthew 18:21-35
