Hello impala63rag, and welcome!
We are delighted that you have discovered something is wrong before it is far too late.
Those who studied with you may be sincere but their highest loyalty belongs to a particular sectarian religious organisation and denomination.
Unfortunately this forces them to bait-and-switch you.
You asked for the Bible and the "truth of the Good News", and their agenda was always ultimately religion.
It is no accident that most followers of the Watchtower call themselves "publishers of the Good News" but are unfamiliar with the "Good News" according to Paul, Moses, Isaiah and Psalms.
Effectively they do not believe in or teach "the truth of the Good News". Ironically though it can be found in their publications, but just not in their hearts or on their lips.
If you send me a PM (via the envelope icon top right of this page) I'd be happy to send you a 1-page summary of the "Good News" in the Watchtower library, which you can compare with the ignorance and blindness of those studying with you.
Maybe not all is lost.
You could ask them to study the "Good News" according to Paul with you, beginning in the book of Romans.
You could work with them to find and mark each occurrence of the phrase "Good News" in Romans (and the rest of Paul's books right through to Hebrews). This link may be of use: WOL.
On my journey I am learning that the highest possible level of spiritual maturity, fulfilment, consciousness, power and intelligence is attained by pursuing the unabridged, explicit and naked gospel (or Good News) to its zenith.
Best wishes on the journey.
