The good Lord knows everybody’s limits and sometimes those are greater than what the person himself may think (especially if the Lord supplies extra, unaccustomed grace). Job’s faith, however the Lord may have helped it in a quiet manner, was sufficient to weather the ordeal. But God wanted Job’s faith to grow. And it did.
Satan went all in and threw EVERYTHING he had at Jesus, but nothing he could do could shake Jesus. Nothing. All the way from manger to being hung to die on the cross, Jesus could not be broken, shaken or stirred away from God.
That, was that. Game over. God absolutely beat Satan to a pulp with Jesus. Nothing Satan can do will change that or undo it. Not that he hasn't tried.
There's been and will be some more temper tantrums, devious schemes and whatnot, which have already killed millions and caused untold and incalculable pain and suffering, until the very end when Satan comes back for the grand finale with everything he's got.
And we know how that ends. We just don't know how we end...
