“Failure to forgive … wasn’t a matter of failing to live up to a new bit of moral teaching. It was cutting off the branch you were sitting on. The only reason for being Kingdom-people, for being Jesus’ people, was that the forgiveness of sins was happening; so if you didn’t live forgiveness, you were denying the very basis of your own new existence.”
-N. T. Wright, The Lord and His Prayer
