H.B.F you have been given a lot of encouragement and advice on here so far that I hope will benefit you .
I can only give you my 2 cents worth that also helps you .I know its not easy .
So here goes :
The G.B.of jehovah`s Witnesses claim that God -Jehovah approved them as the "true' religion and rejected all other religions around the time of 1919 on what the International bible Students as they were then known under Charles Taze Russell were teaching.
The thing is ,if that were true and Jesus christ /Jehovah God did in fact approve of all the teachings that the IBSA preached and taught all of those years ago in 1919 and approved them on that basis .
Then i`m sorry but Jesus Christ /Jehovah God would have to reject them today as his "true religion " simply because the Jehovah`s Witness religion does not preach or believe what they taught back in 1919.
So simply stated if they were approved by God in 1919 on what they believed and taught and now in 2019 they reject as old light what they taught in 1919 and not applicable today ,they would be rejected by Jehovah God and Christ Jesus as the true religion.
they can`t have it both ways .
I hope this helps
Take care .
