Thus in this oneness Jesus Christ is the Mediator, the Reconciler, between God and man. Thus He comes forward to MAN on behalf of GOD calling for and awakening faith, love and hope, and to GOD on behalf of MAN, representing man, making satisfaction and interceding. Thus He attests and guarantees to God's free GRACE and at the same time attests and guarantees to God man's free GRATITUDE.

- Karl Barth
