The-worldly man's peace cannot be maintained but by avoiding consideration and reflection. If he allows himself to think, and properly to exercise his reason, it destroys his quietness and comfort. If he would establish his carnal peace, it concerns him to put out the light of his mind, and turn beast as fast as he can. The faculty of reason, if at liberty, proves a mortal enemy to his peace. It concerns him, if he would keep alive his peace, to stupify his mind and deceive himself, and to imagine things to be otherwise than they are. But with respect to the peace which Christ gives, reason is its great friend.
