But only JW religion portrays Satan more powerful than God
The fact that JW's use the term 'Sovereign' for Jehovah itself implies that they believe that no one is mightier than him.
If someone questions the supreme ruler or monarch of a country, and the monarch decides to give him a reply or satisfy his questions, does that mean that the one questioning becomes greater and powerful than the monarch?
needs validation from Satan as though He waits till Satan is satisfied
To put it this way, JW teaching doesnt imply that Satan is powerful than Jehovah, because:
1. they teach that even imperfect humans can fight Satan and win against him
2. and that Jehovah is not waiting to satisfy Satan, but is waiting to first imprison him and then kill him eternally.
