Because the scriptures they present are about tears being dried and happiness being restored to everyone.
And the many pictures depicting the handicap throwing away their canes and old growing young and loved ones walking out of the graveyards to the waiting arms of their families.
You're right on about that with me. At the time that I went in, my husband had just had his hemipelvectomy. I was around 26 years old. My whole world had changed. I had a handicapped husband. My husband took part in the studing for awhile. He became an approved associate. I remember when he'd get up there with only one leg on crutches (he couldn't wear a prothesis the amputation to part of his pelvis). I had no idea how they were using us. My husband stopped going to the meetings before I did. I'm glad that he never got baptised.
At least this way when they're dad is sick, our daughters don't have a restriction to not visit him.
