I like where you’re going with this.  we need to take care of unfinished business and try as best we can to not hold hate and grudges in our hearts.  Check negative karma with Jesus’ empowering grace.  Buddhists might call it “tonglen” (compassion practice).  Theresians might call it “the little way”.  Whatever it is it is compassion-in-action and I believe Christianity should once again 7 x 70 pick it up again and keep working on it—and Trusting the mysterious Mercy of G-d.
