The theology of the cross reveals that God isn’t a philosophical Monad, or some pure being up yonder. The theology of the cross reveals that God in Christ is humble enough to define His being by concretely becoming flesh and blood humanity, such that we might share with Him who He has always already freely chosen to be: God not without us, but with us (Immanuel), in and by the assumed and vicarious humanity of Jesus Christ. And yet, His being, even in His humiliation as a human, becomes the image within which we are created and recreated, just as the Lamb 
of God was slain before the foundations of the world. In other words, our humanity, as some sort of abstract entity doesn’t circumscribe His in Christ, but His for us, in the εἰκὼν τοῦ θεοῦ (image of God), His humanity circumscribes ours; His humanity is the humanizing humanity whereby a fallen humanity escapes an eternal dissolution into nothingness, and instead realizes what in fact it means to be genuinely human: viz. to live, by grace, in the triune fellowship of the Father, Son, and Holy Spirit.
