Free will is "corrupted nature's deformed darling, the Pallas or beloved self-conception of darkened minds"

He who prays as he ought will endeavor to live as he prays.

The vigour, and power, and comfort of our spiritual life depends on the mortification of the deeds of the flesh.

A man preacheth that sermon only well unto others which preacheth itself in his own soul. And he that doth not feed on and thrive in the digestion of the food which he provides for others will scarce make it savoury unto them; yea, he knows not but the food he hath provided may be poison, unless he have really tasted of it himself. If the word do not dwell with power in us, it will not pass with power from us.

Spiritual wisdom consists in finding out the subtleties, policies, and depths of any indwelling sin... to trace this serpent in all its turnings and windings; be able to say, at its most secret actings, 'This is your old way and course; I know what you aim at.'

Christ is the meat, the bread, the food of our souls. Nothing is in him of a higher spiritual nourishment than his love, which we should always desire.

Let no man think to kill sin with few, easy, or gentle strokes. He who hath once smitten a serpent, if he follow not on his blow until it be slain, may repent that ever he began the quarrel. And so he who undertakes to deal with sin, and pursues it not constantly to the death.
