On the Cross, Jesus avenged us. The Crucifixion was revenge, pure and simple, on behalf of us. It was a total, all out, to-the-death fight, marked by hate of sin and utter contempt for everything that did not have His purity.
But it was an act of extreme love for us. It was an act of extreme mercy for us. It was an act of extreme compassion for us. It was an act of extreme forgiveness for us.
It occurs to me that the ‘deal’ could have been that if Jesus successfully finished the Crucifixion that Satan and demons and hell world be annihilated. But He did not ask for that.
He asked for us. He asked to have us in heaven with Him. He chose to concentrate on paying the ransom. He wanted an eternity with you and me as his prize.
That Cross was the perfect act of revenge. And with the Resurrection, it was revenge with a vengeance.
