Let us say that God is sorrowful about those militaristic commands given to the Israelites that resulted in the death of children.
Maybe God suffers with people who have to make difficult decisions today and the shared suffering is part of the way God identifies with us and brings us comfort.
Yeah, I tried using Moltmann as comfort once to an Afghan teenager in Rawalpindi, Pakistan during the takeover of Kabul by the Taliban, letting him know that God is suffering with him.
A complete whiff -- even when dealing with an affliction whose cause is forces beyond his control -- but as I had received my most recent theological training from Luther at that point, it was all I had.
While Christ does indeed suffer with us when we are oppressed by outside forces, that is not and cannot be the end of the story. A God who only suffers does no one any good. That's why there's a resurrection. The path from the cross to the resurrection may be inscrutable and there may never be a satisfactory answer to the "why?" question this side of the eschaton (and maybe not even then), yet we do know that God is with us, Immanuel, especially in suffering, even as we know that suffering is not the final answer. Resurrection is. Suffering and the grave cannot frustrate the love of our God, and He is not satisfied to leave us in that condition. Rather, he overcomes suffering and the grave, whether in this temporal life or beyond. Healing does not come through suffering; healing comes through resurrection.
Yet there are times -- most of the time, I would say -- where our problem results precisely not from outside forces but from ourselves. When our suffering is self-inflicted as we turn in upon ourselves, seeking what we think is our good in contradistinction to God. It's called sin. And here, it is God who is the problem. It is God who afflicts us, and He does so with His Law, written on our hearts, operative in nature, and revealed in Scripture. Here, it is God who causes us to suffer, who seeks to kill this deformed creature before Him, this creature twisted by sin. This is God's "alien work," but it is still God's work. He puts that creature to death in baptism, in confession and absolution, in the Lord's Supper. Wherever forgiveness is offered and received, a death occurs. But like before, not simply a death but a resurrection. A new creature comes forth, fully cleansed of his sin even as he still bears the scars of his affliction in this life, awaiting for the full redemption and healing that is to come.
Which is all to say that a proclamation of a God who suffers with and comforts us in our suffering, if that's all there is, has little to do with the Law and Gospel, the cross and the empty tomb. It is anemic.
