He could have just written off our rebellion, donkey, but he didn't. Why not?
Part of it is respect for our free will. Had he just negated our rebellion with a wave of his hand, he would have, in effect, said that our ability to choose was of no account, and that we are not truly creatures with free will.
Second, having taught us that our choices matter to US, he showed how much they mattered to HIM by sending his son to die that way. That's how much he values our choice to serve him. He put that up there as a kind of testament to his value of each of us as an individual.
Third, he shares our pain of death. He is a God who holds absolutely nothing back.
Fourth, he shows us that death is not the end of our lives, because if he could re-create the second most powerful person in the universe, he can certainly re-create any one of us. So the dreadful penalty of sin is defanged.
Fifth, if someone had to reconnect the Divine with the earthly, then it would have to be someone we could trust to judge us mercifully - hence, Jesus' earthly ministry.
God is the greatest teacher, and he spares nothing to teach us that in a huge and chaotic universe, we truly do matter as sapient, spiritual creatures who can choose what side to take. Jesus' sacrifice takes on great meaning if we learn to value ourselves.
Does any of this make sense or am I tweaking on caffeine?
