OK,everyone, some of you know and some of you don't that my in-laws raise my step-daughter. We basically have a decent relationship at this point. What my dh and I have learned is that if we can make a theological argument on something that is convincing well - we can usually makeour point. Well my step daughter has gotten increasingly large. It has gone past the baby fat issue. She is 11 years old a half inch shorter than I am and at this point has gotten much larger than I have at 31. At Christmas when I saw her she would fit in a women's 10 now I doubt she will that and that is without her having developed the usual female curves. Her father and I are concerned about her health as well as her self esteem but in-laws seem willing to dismiss it as "baby fat." She has told us her doctor has spoken to her about it but that one week every summer at "Sports Camp" should fix it. She says she does not have time to do sports as she does other things during the school year. I have a degree in Health Science and I know this can cause major issues startin now and can even see it in her breathing.
My issue is this. I want to make an unemotional plea to the in-laws. I know that this is affects:
Body as a temple
Sanctity of Human Life
What other arguments can one think of where this can be sinful?
Oh and I am going to let dh present this to his parents but want to makea clear presentation as it will better impress them. (wierd family dynamic)
