Christ's Government

Wherever you find true wisdom and judgment, there Christ has set up his government; because where wisdom is, it directs us not only to understand, but to order our ways aright. Where Christ (by his Spirit) as a prophet teaches, he likewise as a King (by His Spirit) subdues the heart to obedience of what is taught. That is the teaching which is promised of God, when not only the brain, but the heart itself, is taught. Men do not only know what they should do, but are taught the very doing of it. They are not only taught that they should love, fear, and obey, but they are taught love itself, and fear and obedience itself. Christ sets up his chair in the very  heart, and alters the frame of that, and makes his subjects good, together with teaching them to be good. Other princes can make good laws but they cannot write them in their people's hearts. (Jer. 32:40)…
We learn likewise that men of a poorly governed life have no true judgment: no wicked man can be a wise man. Without Christ's Spirit the soul is in confusion, without beauty and form, as all things were in the chaos before the creation.  The whole soul is out of joint till it is set right again by him whose office it is to restore all things. The baser part of the soul which should be subject, rules all, and subdues that little truth that is in the understanding, holding it captives to base affections. Then Satan by corruption occupies the soul till Christ, stronger than he, comes and drives him out… Christ as a new conqueror changes the fundamental laws of the old Adam, and establishes a government of his own.
