The biggest thing, Jesus paid the ransom, DONE.
IF there was an universal issue [God's RIGHT to rule] to be settled, there is nothing in the bible mentioning it. Satan wanted worship for himself, but he did not come out directly and challenge God's right to rule. Isa 14:14
If there had been a question about God's 'right to rule', then Satan would have totally ignored God's mandate not to kill Job. Just like we can reason out, that Satan had tried to kill Jesus from the moment he was born, but was not allowed to, until God's appointed time.
