R is for
Repent
The breaking of the window is what Christians often only think of as sin. When the breaking of the window is the only problem, then Christians should only "repent" of what they did and try their best not to do it again. Christians should only try their best to live the right way according to God's will. Christians should not go around doing those kinds of things, like breaking windows (dancing, drugs, gambling, cards, living with someone before marrying that person, cheating, swearing, staying home on Sundays, and all that kind of stuff of the Ten Commandments). Being a Christian means your life will change for the better and you won't go around breaking windows anymore.
Jesus, of course, needs to be made part of this story of breaking the window. Jesus is used as the one who forgives the kids for breaking the window. He pays for the broken window (all the hurtful things done that break people and their feelings and bodies) by dying on a cross and rising from the dead. Jesus pays the owner of the house. In fact, Jesus was sent by God to pay for the broken window. God loves the kids who were playing baseball and wants to help them pay for the broken window so the owner of the house who was hurt is made to feel better. Jesus helps the kids come back and say they're sorry--repent--for breaking the window and that they will do their best not to break any more windows.
Jesus is being underused. He is being used, not as a "mediator and propitiator of God's wrath," but as an employee of the Glass Company, the company that fixes broken windows. Or Jesus is a therapist who helps heal feelings; or he is a doctor who helps heal broken or sick bodies. He is not used to give faith in God, because the lack of faith was never a problem. His death is used as a form of barter, something used to pay for the things people have broken, instead of being the means by which God reconciles unlistening and disobedient people to God's own goodness.
