This article by the nephew of American prosperity gospel and healing ministry advocate Benny Hinn is well worth reading - because he explains how he grew up and grew out of what he had been taught. As I read it, I was reminded of the young women who left Westboro Baptist Church (here). These stories are courageous, important and powerful, and serve as a valuable lesson to anyone entrusted with ministry.
By contrast, sometimes the sons/daughters of respected and famous preachers are themselves the cause of concern, as is the case here.
Preachers kids, like Mish Kids, have a challenging life, and charismatic parents/relatives can have influence beyond what they might realise. I guess these three examples illustrate just how that can work out - for good and for ill.
