The DO told us at the recent district assembly @ The Netherlands, that if you have doubts about JW doctrine, you have to remain a strong connection with Jehovah God, because "you are dedicated to Jehovah and NOT to an organisation".
Later on a very old brother was interviewed and he gave the counsel "Keep your doubts about doctrine in a refrigiator, just wait and see". The DO asked him "how many refrigiators do you have? The brother told him "I have 3 refrigiators full".
