All other religions have myths that show Satan as inferior to God Almighty. But only JW religion portrays Satan more powerful than God through their teaching of “Issue of Sovereignty” which implies God Almighty needs validation from Satan as though He waits till Satan is satisfied which has not happened even after killing of Jesus 2000 years ago and things like ethnic cleansing, spilling of oceans of blood …. etc.
Venus I basically agree with you on this as JWs have come up with the universal sovereignty doctrine because the kingdom of God hasn't arrived yet, as you say even with their belief in the ransom sacrifice of Jesus.
Probably because they don't believe everyone goes to heaven they've come up with an answer as to why our reward of a paradise earth has taken so damn long to get here.
We're waiting for God to give an answer to Satan, as in Job's account, proof that people serve him out of love and not for reward. As with everything the JWs believe they keep having to think of ridiculous reasons why paradise has been delayed.
