Had a sit down chat with an elder who is aware of my doubts. We were on the subject of new light, i was saying that if the org changes a teaching then the old teaching was wrong and cannot qualify as truth at the time it was taught, so where did the falsehood come from?
His response was the GB is imperfect!! I said that its a cop out when things they teach as truth are spirit directed, but when they get it wrong its imperfection. His reply was that Jesus after heartfelt prayer selected Judas. So Jehovah allows his spirit directed people to get things wrong and this is no reflection on their status as spirit directed!
