The law is a system, set, an organization for the intellect, a judge that sits outside, and static. By delineating right and wrong behaviors intellectually--reasonably, the law takes responsibility for keeping or rejecting those behaviors away from the human heart—which is the storehouse and originator of all action whose master is and will be only its Creator. The law becomes something it can’t. It becomes like a conscience. But because the law operates at the level of the intellect, it can’t be related with like the conscience. The conscience is deeper. It speaks from somewhere else. The law pretends to be the human heart—and the human mind is too often glad of this. The law acts as a replacement.
Now, the law may indeed instruct and prod the conscience, but it is neither the conscience, nor can it speak with it directly, nor love, nor cherish it. The law may prod the conscience to recognize sin (wrongness), but it does not shed light!—can not—reveal glory! which is peace, joy, and oneness with God hidden in righteousness (rightness)! Only faith can! Only trust can! It is impossible for the law to make men right the moment it is seen by men’s logic—for it no longer requires men’s faith. But righteousness is always, and only, and ever a step; a movement away from what is dark and towards what is light—on faith. It is obedience to what is necessarily unreasonable to the intellect because it demands belief. And demands it now.
