I am reading a book entitled Sin and the Unfolding of Salvation by David Gracey. David Gracey was the theology professor at Spurgeon's College. I doubt that I will do a complete review of this book when finished but I have found it to be very thought provoking. I did find something I read last night very interesting in relation to the law. I want to share this portion here.
"It is now sufficiently apparent what is meant by public righteousness and the satisfaction rendered to it. But at this point we must be careful not to allow ourselves to regard this righteousness in any restricted sense. We must not confine it exclusively to the administrative acts, or even principles, of the Divine Government. It must also include that law which is to men the supreme expression of Divine righteousness in words. It is this law which enable us to know with certainty what is morally right. It is this law which furnishes the perfect standard whereby we can estimate the rectitude of the Divine procedure. It underlies the whole Government of God. In the sublime language of the Psalmist its position is this, "Justice and judgment are the habitation of Thy throne" (Psalms 89:14). In the equally sublime imagery of the Holy of Holies, the tables of the law were enclosed in the Ark of the Covenant, and lay beneath the golden Mercy Seat, where the Shekinah shone between the Cherubim. It is this law that is presented to us by Revelation, and enjoined by the authority of God. Higher than this, when fully interpreted, as it has been by Christ, no righteousness can rise, no holiness can reach. It is the expression of the Divine nature and of the Divine will. Therefore it is in its principles eternal and of universal obligation. For all the changing phases of the Divine Administration, there has been no change in the principle of the law. The expression may have altered, but not the precepts. These have been one and the same both in Eden and outside its guarded gates; the same to the world before the Flood and in Patriarchal times; the same from Sinai to Calvary; the same from Calvary right onward till the Great White Throne appears, and then the same forever. This law, that comes from above, is the true objective counterpart to that which is within the human breast, and is subjective in the conscience. To the meaning of the handwriting of God, the Divine hieroglyphics in the human soul, this is the only and the infallible key. When touched by this, the heart of man discloses its inmost secrets, and admits the authority of the Divine Legislator, bowing before the presence of the Judge of all. This is the law by which we discern the righteousness of the Government of God, the law which forms the constitution of God's Sovereignty, and this we understand to be that law of righteousness whose claims the Saviour satisfied."
