It's much more deeply seated than that, Grace.
Sis has some psychological problems, and I am the unwitting focus for these. It is absolutely nothing to do with me. She has some sort of anger management issues (I believe) and I am a "safe" focus for these, where she dare not express them to the person(s) concerned. I have sought counselling/reconciliation with the aid of a totally independent minister associate, my Mum's minister, whom I hardly know (my sister would know her much better) - it was a disaster and the minister was shocked at the violence of sis's litany of issues.
I believe it is a spiritual issue. I (and others) pray for her, and for the other people caught up in this. It causes much deep hurt within family and friends. But there is nothing to be done until she herself recognises that she has a problem that needs to be addressed in some way.
She is a nice caring (but controlling) person to everyone else and if anyone met her outside of any context that involves me, they would probably like her. Meet her in any context that has a connection to me, and they would get the cold shoulder (at best).
To bring this back to the context of this thread, she is loved, treated well and kindly, but every effort is turned back. It is rebuffed, and worse, seen as some effort to manipulate her or control her life in some way. It is hard to love someone like that, but I do and nonetheless would do whatever I could to help her and would never do anything to harm her.
Did not the Lord seek us out when we were totally unlovable, rejecting, and vile? Does he not welcome us back with open arms and complete forgiveness? Does he not hanker after reconciliation? As soon as we are ready, we are embraced in his love.
And that is my deep desire, with my sister - and for all others that are lost in their worlds of hatred, misery, violence, addiction, or whatever their problem is.
