Kathy,
There is definitely a blind issue and I would easily guess a lie has been
planted in this area which is pretty easy to fix. Getting these kids to sit
down and pray about it with you, however, is easier said than done and
especially, in Gretchen's case, when rebellion has become a part of the
picture. Rebellion is a sign of witchcraft according to Scripture, too, so
at least we know what we are dealing with.
Phil.
