"When they make adjustments, or we are given a new or clearer understanding, I usually just think... 'Why didn't we believe that all along?' I hear it, I check the scriptures, and realize they are right. For me, and I can only speak for myself of course, I am glad that we keep adjusting our path, so we can follow what the Bible really says."
This seems to be a common remark from JWs and once again she is not just speaking for herself, she's repeating an ingrained thought control.
Examining this statement is interesting.
If she were to reconsider what she was originally taught, without knowing the new teaching, would she still believe what that original teaching was? Of course she would. But and the big but is, that it was obviously wrong (from a JW standpoint) so why weren't questions being asked and why did she not closely examine this teaching?
"So we can follow what the bible really says" This is acknowledgement that they don't have the truth because they don't always follow what the bible says, otherwise they wouldn't need to make changes.
Who is telling her to make changes in her understanding? Is it the bible or is it men?
What she is really saying is that she loves the new teaching because it is easier to explain whilst witnessing and is easier to understand. She doesn't care about the truthfullness of the old teaching or the new teaching. As long as it comes from the organization she will find some way to adapt it into her own thinking.
You haven't, as yet, forced her hand into having to say that we need to wait on Jehovah for the answer to that question but she seems to present herself as a person who knows all the answers. This is what makes a JW such a prideful person, they think they have all the answers and this isn't from their own understandings, reasearch and thoughtful consideration but because they have been spoonfed those answers. Even when they know they are wrong they are right because they can turn to some twisted teachings for a reply that sounds good.
Get ready for her to use the statement about having to wait on Jehovah for a specific answer.
