Eder is like Son Goku or the Power Ranger's Megazord. He could go all out from the start and vanquish all villains, but that wouldn't make for a good show. So he bides his time and strikes when we need him the most.
We are blessed.
"And when Eder saw the breadth of his domain, he wept for there were no more worlds to conquer."
'What good will it be for someone to gain the whole world, yet forfeit their soul?' Matthew 16:26
The world shall be ready soon..
